Commentaries and Reflections

Commentary by T Krishnamacharya:

Abhyāsa is the practice of reflecting on the difference
between the nature of Jīva and the nature of Prakṛti,
which brings momentary tranquillity to the mind and
eventually leads to complete and sustained mental tranquillity.”

Commentary by TKV Desikachar:

“How do you know the use of the right means is good?”

“The spirit of Abhyāsa is to always verify the best means to go from one step to another.”

“The starting point for Abhyāsa is not the mind,
it is other than the mind.
The moment the mind takes over you are in difficulty.”

“Any Abhyāsa is only for the mind,
you cannot go beyond that point.”

Commentary by Paul Harvey:

Meditation is about the quality of the effort,
rather than the fruit of the time.”

“In Jñāna Dhyānam the most
difficult exercise for the mind is
the one of not exercising the mind.”

“In Sūtra 1.13 Patañjali succinctly
defines the aim of Abhyāsa as
the effort to remain there.
What is the ‘effort‘ mentioned here?
Where is the ‘there‘ mentioned here?”
