“These five Kleśa surround the heart of every individual.
They are related to the three Guṇa known as Sattva, Rajas and Tamas.
As long as one chooses not to inquire into the true nature of one’s self and acts mechanically,
they will unknowingly contribute to the dominance of the Kleśa.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter Two verse 3
