Two Yoga Samhitas: Gheranda Samhita and Goraksha Samhita

The first aspect of yogic practice described in Gheraṇḍa Samhitā is ṣaṭkarma, the six yogic cleansing practices. Their practice is important to get rid of diseases from the body and purify it properly. The second aspect of yogic practice discussed is the āsana. The importance of āsana practice is that they help create firmness and stability in the body. The third aspect of practice described is the mudrā which is used to control the flow of prāṇa and retain and circulate it within the body. The fourth aspect of practice he talked is pratyāhāra. According to Sage Gheraṇḍa, when body is purified through ṣaṭkarma, it is made firm and stable by āsana and prāṇa is controlled and retained by mudrā, then one can naturally do the practice of pratyāhāra. The fifth aspect of practice he taught is prānāyāma. In most of the prānāyāma practices he included mantras with them. Practice of prānāyāma with specific mantras creates direct impact on energy field within the body and mind through the vibrations of the mantras which eventually contribute for the expansion of awareness.
