Commentaries and ReflectionsT 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.”
“How do you know the use of the right means is good?”Paul Harvey:
Practice is the effort to remain there.
Meditation is about the quality of the effort rather than the fruit of the time.
