Patanjali set out his definition of yoga in the Yoga Sutras as having eight limbs (अष्टाङ्ग aṣṭ āṅga, “eight limbs”):

1. Yamas
   1. Ahimsa (अहिंसा) Nonviolence, non-harming other living beings
   2. Satya (सत्य): truthfulness, non-falsehood
   3. Asteya (अस्तेय): non-stealing
   4. Brahmacharya (ब्रह्मचर्य): chastity, marital fidelity or sexual restraint
   5. Aparigraha (अपरिग्रह): non-avarice, non-possessiveness
2. Niyama – observances
   1. Saucha (Cleanliness)
   2. Santosha (Contentment)
   3. Tapas (Austerity)
   4. Svadhyaya (Selfstudy)
   5. Ishvara Pranidhana (Devotion to the Lord)
3. Āsana – A physical posture in which one can be steady and comfortable.
4. Prāṇāyāma – control of the prana (breath)
5. Pratyahara – withdrawal of the senses
6. Dhāraṇā – concentration
7. Dhyāna – meditation
8. Samādhi – absorption

Samyama – integration

• Fixing the consciousness on one point or region is concentration (dhāraṇā).
• A steady, continuous flow of attention directed towards the same point or region is meditation (dhyāna).
• When the object of meditation engulfs the meditator, appearing as the subject, self-awareness is lost. This is samādhi.
• These three together – dhāraṇā, dhyāna and samādhi – constitute integration or saṃyama.
• From mastery of saṃyama comes the light of awareness and insight.
• Saṃyama may be applied in various spheres to derive its usefulness.
