Q: What are the hindrances to the realization of Reality?

Bhagavan: Memory chiefly, habits of thought and accumulated tendencies.

Q: How to get rid of these?

Bhagavan: Find out the Self through meditation in this manner. Trace every thought back to its origin which is the ‘I’- thought; never allow thought to go on. If it does it will be unending. If you take it back to the source, thoughts will die of inaction, for the mind exists by thought; take away thought and there is no mind. As each doubt and depression arises ask yourself, ‘Who is it that doubts? Who is depressed?’ Tear everything away until there is nothing but the source left.
Live only in the present.
