We have said how discrimination is the most important qualification to have, i.e., to know the difference between the Self and not-Self. The problem is that we get confused between the Self and the not-Self. In fact, the association of the Atman (the true Self) with the mind makes us think that we are the mind. Whatever the mind thinks, you think you are. This is a big problem, the biggest problem. That is why discrimination is the most important qualification.
