“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.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 2

“Taking care within the ‘small‘ arisings
is directly related to our capacity to
take care within the ‘big‘ arising.”
– Paul Harvey on Yoga Sūtra Chapter Two verse 2

“All these Kleśa are variable in their potency.
They can be so weak, that they hardly matter.
Sometimes they take a feeble form,
when they can be easily contained.
If not they rise to dominance.
When in domination, only one takes over.
For example in the most evolved stage
when Rāga is dominant, other Kleśa
such as Dveṣa are not apparent.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 4

“Kleśa are not always dominant.
Through Kriyā Yoga they become weaker and weaker.
How is it possible to completely subdue them?
No mental effort can help as Mind is the storehouse of the Kleśa.”
– T Krishnamacharya on Yoga Sūtra Chapter Two verse 10
