Commentaries and Reflections

Commentary by T Krishnamacharya:

Commentary by TKV Desikachar:

Commentary by S Ramaswami:

“By the practice of Pratyāhāra, the highest control of the Indriya is obtained.

In this context Patañjali is referring to the Jñāna Indriya:
Sight, Sound, Touch, Taste, Smell.

The Karma Indriya are not included and one could say that they are controlled by the Yama and Niyama
i.e. Speech, Grasping, Motion, Excretion, Reproduction

Although the senses aren’t withdrawn they are under control.”

Commentary by Paul Harvey:

Pratyāhāra is both a Sādhana and a Siddhi.
In that, it is a Siddhi of Prāṇāyāma,
as well as a Sādhana for Dhāraṇā.”
