Commentaries and Reflections

Commentary by T Krishnamacharya:

“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.”
