Commentaries and ReflectionsT Krishnamacharya:
“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.”
“A particular Dharma is not there,
but somewhere we feel it is there.”
“Wrong perception is false knowledge that has no basis.”
“Viparyaya is seeing what we want to see.
or not seeing what we need to see.”
