4.3 Ashtanga Yoga: The Bahiranga Limbs (Yamas, Niyamas, Asana, Pranayama)

For a certified Yoga Protocol Instructor (YPI), teaching the first four limbs with scriptural accuracy bridges the gap between mechanical gym routines and authentic Indian tradition.

The Architecture of Ashtanga Yoga (PYS 2.29)

Patanjali enumerates the eight constituent limbs in Sutra 2.29:

यमनियमासनप्राणायामप्रत्याहारधारणाध्यानसमाधयोऽष्टावङ्गानि Yama-Niyama-Asana-Pranayama-Pratyahara-Dharana-Dhyana-Samadhayo'shtav Angani (Yoga Sutra 2.29) "The eight limbs of Yoga are: Yama (restraints), Niyama (observances), Asana (posture), Pranayama (breath regulation), Pratyahara (sense withdrawal), Dharana (concentration), Dhyana (meditation), and Samadhi (absorption)."

The Classification: Bahiranga vs. Antaranga

Classical commentators divide these eight limbs into two major functional tiers:

1. Bahiranga Yoga (External / Preparatory Limbs): Limbs 1 through 5 (Yama, Niyama, Asana, Pranayama, and Pratyahara). These practices harmonize the practitioner's social relationships, physical physiology, neuro-respiratory rhythms, and sensory doors, shielding the conscious mind from external chaos.
2. Antaranga Yoga (Internal / Meditative Limbs): Limbs 6 through 8 (Dharana, Dhyana, and Samadhi). These practices operate entirely within the subjective field of consciousness to dissolve mental modifications and reveal Purusha.

The Five Yamas: Universal Social Morality (PYS 2.30)

The Yamas represent ethical restraints that govern an individual's interaction with the external social environment. Rather than repressive moral taboos, they are energetic boundaries that prevent psychic leakage and karmic entanglements:

    Non-Violence   Truthfulness   Non-Stealing     Continence    Non-Hoarding

1. Ahimsa (Non-Violence / Non-Injury) — PYS 2.35

• Definition: The complete absence of ill-will, aggression, malice, and cruelty toward any living being at all times, in thought, word, and physical deed (Manasa, Vacha, Karmana). Ahimsa is the foundational mother of all Yamas; the remaining four are expressions of non-violence.
• Fruit (Siddhi - PYS 2.35):

  "Ahimsa-pratishthayam tat-sannidhau vaira-tyagah" "When a yogi is firmly established in Ahimsa, all living beings completely abandon their mutual enmity and hostility in the yogi's presence." Even natural predators (such as a tiger and a deer) coexist peacefully in the aura of an enlightened master of Ahimsa.

2. Satya (Truthfulness) — PYS 2.36

• Definition: Uncompromising alignment between reality, thoughts, and spoken words. However, Sage Vyasa emphasizes that speech must be both truthful and benevolent (Hita and Priya). If speaking a literal truth causes unjustified harm to an innocent being, it is not yogic Satya.
• Fruit (Siddhi - PYS 2.36):

  "Satya-pratishthayam kriya-phala-ashrayatvam" "When truthfulness is firmly established, actions bear fruit unfailingly in accordance with the yogi's words." The words of a perfected yogi acquire sovereign efficacy (Vak-Siddhi); whatever is uttered manifests into reality.

3. Asteya (Non-Stealing / Non-Covetousness) — PYS 2.37

• Definition: Refraining from unlawfully taking, desiring, or coveting that which belongs to another. It includes resisting intellectual plagiarism, taking undue credit, and harboring hidden envy.
• Fruit (Siddhi - PYS 2.37):

  "Asteya-pratishthayam sarva-ratnopasthanam" "When non-stealing is firmly established, all precious jewels and treasures spontaneously present themselves to the yogi."

4. Brahmacharya (Continence / Energy Conservation) — PYS 2.38

• Definition: The preservation, conservation, and sublimation of vital creative and sexual energy (Virya). For a householder (Grihastha), it means fidelity to one's spouse and moderate sexual conduct; for an ascetic (Sannyasi), it implies complete celibacy in thought, word, and deed.
• Fruit (Siddhi - PYS 2.38):

  "Brahmacharya-pratishthayam virya-labhah" "When continence is firmly established, supreme vigor, vitality, courage, and radiant spiritual power (Ojas) are attained."

5. Aparigraha (Non-Possessiveness / Non-Greed) — PYS 2.39

• Definition: Relinquishing the compulsive impulse to accumulate, hoard, or cling to unnecessary material possessions, gifts, or favors beyond one's genuine survival needs.
• Fruit (Siddhi - PYS 2.39):

  "Aparigraha-sthairye janma-kathanta-sambodhah" "When non-possessiveness becomes steadfast, complete intuitive knowledge of the how, why, and wherefore of past and future births is revealed." By eliminating material clinging, the mind recognizes that it existed before acquiring the present body and will exist after departing it.

The Sarvabhauma Mahavrata (The Great Universal Vow) — PYS 2.31

Patanjali explicitly elevates the five Yamas beyond regional customs or situational ethics:

जातिदेशकालसमयानवच्छिन्नाः सार्वभौमा महाव्रतम् Jati-Desha-Kala-Samaya-Anavachchinnah Sarvabhauma Mahavratam (Yoga Sutra 2.31) "These vows are universal (Sarvabhauma), the Great Vow (Mahavrata), unconditioned and unrestricted by birth/caste (Jati), geographic place (Desha), historical time (Kala), or societal circumstance (Samaya)."

• Jati: A fisherman cannot justify killing fish by claiming it is his hereditary caste occupation.
• Desha: A person cannot pledge non-violence at a holy temple while indulging aggression in a marketplace.
• Kala: One cannot practice truthfulness only on sacred holidays while lying on weekdays.
• Samaya: A soldier or king cannot suspend ethics for arbitrary personal convenience.

The Five Niyamas: Personal Self-Purification (PYS 2.32)

While the Yamas govern outward conduct, the Niyamas are internal spiritual observances that purify the practitioner's body, mind, and intellect:

शौचसन्तोषतपःस्वाध्यायेश्वरप्रणिधानानि नियमाः Saucha-Santosha-Tapah-Svadhyayeshvara-pranidhanani Niyamah (Yoga Sutra 2.32)

   (Inner/Outer)   (Unexcelled Joy) (Willpower)   (Scriptures)    (Surrender)

1. Saucha (Purity / Cleanliness) — PYS 2.40–2.41

• Twofold Dimensions:
  1. Bahya Saucha (External Purity): Bodily hygiene, bathing, consuming pure Sattvic food, and practicing Shatkarmas.
  2. Abhyantara Saucha (Internal Purity): Washing the mental lake of jealousy, lust, greed, and hatred through noble thoughts (Maitri, Karuna).
• Fruits (Siddhis):
  • External Fruit (PYS 2.40): Detachment from one's own physical body (Sva-anga jugupsa) and cessation of obsessive physical clinging to others.
  • Internal Fruit (PYS 2.41): Purification of mental nature (Sattva-shuddhi), joyful cheerfulness (Saumanasya), one-pointed concentration (Ekagrata), mastery of the senses (Indriyajaya), and fitness for self-realization (Atmadarshana-yogyatva).

2. Santosha (Contentment) — PYS 2.42

• Definition: Cheerful, serene acceptance of whatever comes naturally by destiny, without craving for more or lamenting what is missing. It is contentment with conditions outside one's control.
• Fruit (Siddhi - PYS 2.42):

  "Santoshad anuttamah sukha-labhah" "From contentment, unexcelled, supreme happiness (Sukha) is attained." Worldly pleasures derived from sensory gratification are finite; the joy of Santosha is self-born and permanent.

3. Tapas (Disciplined Austerity) — PYS 2.43

• Definition: The cheerful endurance of physical and mental dualities (Dvandvas—cold and heat, hunger and thirst, comfort and fatigue) to burn away somatic lethargy and strengthen the will.
• Fruit (Siddhi - PYS 2.43):

  "Kaya-indriya-siddhir ashuddhi-kshayat tapasah" "Through the destruction of impurities by Tapas, perfection and mastery of the body and sensory organs are attained."

4. Svadhyaya (Self-Study / Scriptural Reflection) — PYS 2.44

• Definition: Dedicated study of spiritual scriptures (Upanishads, Bhagavad Gita, Yoga Sutras) combined with the rhythmic chanting of sacred mantras (such as OM) to awaken self-inquiry.
• Fruit (Siddhi - PYS 2.44):

  "Svadhyayad ishta-devata-samprayogah" "From self-study and sacred chanting, direct communion with one's chosen deity or divine ideal (Ishta Devata) is established."

5. Ishwara Pranidhana (Devotional Surrender) — PYS 2.45

• Definition: Offering all thoughts, actions, and fruits to the Divine, transcending egoic entitlement.
• Fruit (Siddhi - PYS 2.45):

  "Samadhi-siddhir Ishwara-pranidhanat" "From devotion and surrender to Ishwara, the perfection of Samadhi is attained."

Psychological Remedy: Pratipaksha Bhavanam (PYS 2.33–2.34)

What should a practitioner do when destructive, violent, or deceitful thoughts surge into the mind? Patanjali offers a brilliant cognitive behavioral technique:

वितर्कबाधने प्रतिपक्षभावनम् Vitarka-badhane Pratipaksha-bhavanam (Yoga Sutra 2.33) "When plagued by negative or destructive thoughts (Vitarkas), cultivate opposite benevolent thoughts (Pratipaksha Bhavana)."

• Vitarkas (वितर्क): Destructive, unwholesome thoughts—such as the urge to harm, lie, steal, or retaliate.
• Analysis of Vitarkas (PYS 2.34): Patanjali explains that negative thoughts are either:
  1. Performed directly by oneself (Krita),
  2. Instigated or caused to be done through others (Karita), or
  3. Approved and condoned when done by others (Anumodita). They are motivated by greed (Lobha), anger (Krodha), or delusion (Moha), occurring in mild (Mridu), medium (Madhya), or intense (Adhimatra) degrees.
• The Remedial Strategy: Rather than repressing hatred with violent willpower, the practitioner reflects: "These unwholesome thoughts result in endless ignorance and agony (Dukhkha-ajnana-ananta-phala). Why should I drink the poison of malice?" The mind is immediately redirected toward cultivating active friendliness (Maitri) and compassion (Karuna).

Asana in Classical Patanjala Yoga (PYS 2.46–2.48)

Modern practitioners often equate Yoga with complex bodily gymnastics. In striking contrast, Patanjali dedicates only three brief sutras to Asana, defining it entirely as a meditative seat:

1. The Classical Definition (PYS 2.46)

स्थिरसुखमासनम् Sthira Sukham Asanam (Yoga Sutra 2.46) "Asana is that posture which is steady (Sthira) and comfortable / joyful (Sukha)."

• Sthira (स्थिर): Motionless, firm, stable, and unyielding. The physical spine is erect without slouching, shaking, or collapsing.
• Sukha (सुख): Comfortable, agreeable, relaxed, and devoid of pain, muscular spasms, or agonizing strain.

2. The Methodology of Perfection (PYS 2.47)

प्रयत्नशैथिल्यानन्तसमापत्तिभ्याम् Prayatna-shaithilya-ananta-samapattibhyam (Yoga Sutra 2.47) "Asana is perfected through the relaxation of all conscious effort (Prayatna Shaithilya) and by absorption of the mind in the infinite (Ananta Samapatti)."

• Prayatna Shaithilya: Ceasing all unnecessary muscular tension, softening facial muscles, relaxing the diaphragm, and breathing effortlessly.
• Ananta Samapatti: Contemplating the limitless cosmos, boundless sky, or the cosmic serpent Ananta Shesha, who effortlessly upholds the universe. The sense of physical bodily boundaries dissolves.

3. The Fruit of Asana (PYS 2.48)

ततो द्वन्द्वानभिघातः Tato Dvandva-anabhighatah (Yoga Sutra 2.48) "From that perfection, the yogi is no longer afflicted or victimized by the dualities of opposites (Dvandvas)."

• The practitioner becomes immune to physical heat and cold, physical comfort and fatigue, praise and blame.

---

Pranayama in Classical Patanjala Yoga (PYS 2.49–2.53)

Once physical posture is steady and unmoving, the practitioner graduates to breath regulation:

1. The Classical Definition (PYS 2.49)

तस्मिन्सति श्वासप्रश्वासयोर्गतिविच्छेदः प्राणायामः Tasmin Sati Shvasa-prashvasayor Gati-vicchedah Pranayamah (Yoga Sutra 2.49) "That posture having been perfected, Pranayama is the cessation (or intentional regulation of the intervals) in the movements of inhalation (Shvasa) and exhalation (Prashvasa)."

• Tasmin Sati: "That condition being fulfilled"—Patanjali establishes an uncompromising prerequisite: Pranayama cannot be practiced fruitfully until Asana has achieved stability and comfort.
• Gati-vicchedah: Breaking, modifying, extending, and arresting the automatic habitual rhythm of the breath.

2. The Four Types of Pranayama in Patanjali (PYS 2.50–2.51)

Unlike Hatha texts that enumerate specific techniques like Nadi Shodhana, Ujjayi, and Bhastrika, Patanjali categorizes Pranayama into four functional phases:

1. Bahya Vritti (External Operation / Retention): Exhaling the breath and holding the air out (Rechaka-Kumbhaka).
2. Abhyantara Vritti (Internal Operation / Retention): Inhaling deeply and holding the breath inside (Puraka-Kumbhaka).
3. Stambha Vritti (Stationary / Suspended Retention): Suspending the breath suddenly and completely at any point in the cycle, like water poured on red-hot stone that instantly freezes.
   • Parameters (PYS 2.50): These three are regulated by space (Desha—nasal location), time (Kala—matras or duration), and number (Sankhya—count of breaths), becoming long (Dirgha) and subtle (Sukshma).
4. Bahyabhyantara-vishayakshepi (The Fourth Transcendental State - PYS 2.51):
   • Transcending both the external and internal spheres. This effortless, spontaneous cessation of breath occurs naturally during deep meditative absorption without any deliberate mental contrivance.

3. The Fruits of Pranayama (PYS 2.52–2.53)

• Sutra 2.52: "Tatah kshiyate prakashavaranam"—"Thereby, the veil that covers the inner light of discriminative wisdom is destroyed."
• Sutra 2.53: "Dharanasu cha yogyata manasah"—"And the mind acquires fitness and qualification for sustained concentration (Dharana)."
