Visions of God have their place below the plane of Self-Realisation.

Devotee:  What is the relation between Brahman and Isvara?

Ramana Maharishi:  Brahman is called Isvara in relation to the world.

Devotee:  Is it possible to speak to Isvara as Sri Ramakrishna did?

Ramana Maharishi:  When we can speak to each other why should we not speak to Isvara in the
same way?

Devotee:  Then why does it not happen with us?

Ramana Maharishi:  It requires purity and strength of mind and practice in meditation.

Devotee:  Does God become evident if the above conditions exist?

Ramana Maharishi:  Such manifestations are as real as your own reality. In other words, when you identify yourself with the body as in jagrat you see gross objects; when in subtle body or in mental plane as in svapna, you see objects equally subtle; in the absence of identification as in sushupti you see nothing. The objects seen bear a relation to the state of the seer. The same applies to visions of God. By long practice the figure of God, as meditated upon, appears in dream and may later appear in jagrat also.
