Commentaries and Reflections

Commentary by S Ramaswami:

There has been a progressive transformation of the mind towards Nirodha.
We presumably have learnt everything there is to know about Prakṛti.
All the Siddhi have been discussed, now only Kaivalya is left.

Commentary by Paul Harvey:

“The Book on Freedom

“In the Yoga Sūtra, the pre-eminent text on Dhyānam within Yoga.
Chapter One is about the Refinement of the practice of Dhyānam;
Chapter Two is about the Preparation for the practice of Dhyānam;
Chapter Three is about the Outcome of the practice of Dhyānam;
Chapter Four is about the Goal of the practice of Dhyānam.”
