What obstructs one from seeing God?

What obstructs one from seeing God?

Maya is nothing but the egotism of the embodied soul. This egotism has covered everything like a veil. 'All troubles come to an end when the ego dies.' If by the grace of God a man but once realizes that he is not the doer, then he at once becomes a Jivanmukta. Though living in the body, he is liberated. He has nothing else to fear.

This maya, that is to say, the ego, is like a cloud. The sun cannot be seen on account of a thin patch of cloud; when that disappears one sees the sun. If by the grace of the guru one's ego vanishes, then one sees God.
