Central focus: The practical eight-limbed (ashtanga) path for beginners
Audience: The aspirant whose mind is still distracted — the householder yogi
Summary
Patanjali pivots from describing the goal to handing the seeker a practical kit. He introduces Kriyā Yoga (tapas + svādhyāya + Īśvara-praṇidhāna), the five kleśas (afflictions) that bind us, the doctrine of karma and its fruits, and finally the first five of the eight limbs (aṣṭāṅga): yamas, niyamas, āsana, prāṇāyāma, pratyāhāra. This is the chapter every modern yoga practitioner unknowingly inherits.
Key concepts
- ●Kriyā Yoga: tapas (discipline) + svādhyāya (self-study) + Īśvara-praṇidhāna (surrender)
- ●Five kleśas: avidyā, asmitā, rāga, dveṣa, abhiniveśa
- ●Heyaṁ duḥkham anāgatam — future sorrow can be averted
- ●The 5 yamas (ahimsa, satya, asteya, brahmacharya, aparigraha)
- ●The 5 niyamas (saucha, santosha, tapas, svadhyaya, isvara-pranidhana)
- ●Āsana: sthira-sukham āsanam (steady + comfortable)
- ●Prāṇāyāma + pratyāhāra (breath + sense-withdrawal)
