Ashtanga (eight limbs of yoga)

Ashtanga yoga (Sanskrit: अष्टाङ्गयोग, romanized: aṣṭāṅgayoga, "eight limbs of yoga") is Pātañjali's classification of classical yoga, as set out in his Yoga Sūtras. He defined the eight limbs as yama (abstinences), niyama (observances), āsana (postures), prāṇāyāma (breath control), pratyāhāra (withdrawal of the senses), dhāraṇā (concentration), dhyāna (meditation), and samādhi (absorption).
