Guruji, truth exists, then why is there need for its authentication?
Demanding proof is a characteristic of the mind. Feelings do not ask for proof, the mind does. To satisfy and quiet the mind, proof is needed. But just holding on to it is also an obstacle. That is why in the tendencies of the mind pramana (proof), viparyaya (wrong knowledge), vikalpa (fantasy), nidra (sleep), smritayah (memory), all of these are considered tendencies, and one has to detach from these. Their restraint is yoga.
You cannot eliminate proof. For as long as the intellect is there, it will demand proof. And there is no need to eliminate it. Just be aware of it and move on.
'Yoga buddhi paratattva sah', the Self or God element is beyond intellect.
