Commentaries and Reflections
Commentary by T Krishnamacharya:
“What are the effects of Kriyā Yoga?
Samādhi Bhāvana –
The ability to pursue the right practice that brings one closer to Īśvara.
Kleśa Tanū Karaṇa –
Reduction of those obstacles that we have somehow acquired through wrong actions,
leading to undesirable and bitter experiences.”
“Kriyā Yoga emphasises that the Kleśa cannot be reduced instantly.
It is a gradual process.
Further Kleśa can only be reduced to the limit they become ineffective.
They cannot be destroyed.”
