“Even when our understanding is consistent with our perception or repeated experience,
it does not necessarily indicate a fact.
For instance, if we assume that a person is a woman simply because that person is dressed in a woman’s clothes, this is called Viparyaya or mental activity that is based on something other than fact.
Viparyaya, then, is comprehension based on a perceived characteristic in the observer,
which leads to false assumptions.”
– T Krishnamacharya’s commentary to Yoga Sūtra Chapter One verse 8

“If Śarīra leads Ātma, there is Kleśa.
The cause of this is Karma Vāsana and Mithyā Indriya.”
– T Krishnamacharya commentary on Yoga Sūtra Chapter Two verse 2
