Question
If God exists why doesn’t he want to be seen?
Answer
The Lord is all around you, but you cannot see God because you have since the instance of your birth been bombarded by your senses to perceive the world. Your senses have been bombarding you to see the outer world and not God. Your mind has been hypnotized into seeing this world alone, what is needed is to be de-hypnotized. This hypnotization is called Adhyasa, or superimposition. We see Reality, but it is distorted through maya. In many scriptural instances it is compared to silver in mother-of-pearl. The shell is real, but the silver on the shell is not real.
Sankara says that it is not through learning, or scriptural study, that the Lord is seen, but only through an intense hankering. Ramakrishna Paramahamsa told the story (Gospel of Sri Ramakrishna) of the man who asked his guru what was necessary to see God. The guru took him to a river and had him stand in it next to him. The guru then suddenly pushed the man's head under water. After a while, he let him above the water. The guru said "What did you feel?" The man replied "The intense desire for a breath of air completely consumed me." and the guru responded "When you have the same longing for God as you had for a breath of air, you will see God."
The Mundaka Upanishad (III. ii. 3.) says:
This Self is not attained through study, nor through intellect, nor through much hearing. By the very fact that he (the aspirant) seeks for It [vrnute tena - seeks to reach by that fact of hankering], does It become attainable; of him this Self reveals Its own nature.
Swami Shivananda (disciple of Ramakrishna Paramahamsa) says (For Seekers of God):
Spiritual efforts without sincere love of God are fruitless. Sincere love is what counts. The Master [Ramakrishna] used to say that when the three attachments--that of a devoted wife to her husband, of a mother for her child, and of a miser for his wealth--become one, then one realizes God. If anyone feels the same intense longing as would result if these three attachments were united, only then does he have God-vision. Sincere love brings God-realization and in that alone is genuine peace and joy.
Why is there no human description of God? Because God is beyond description. There are no words to describe God. Krishna says (Gita XI. 12.):
If the radiance of a thousand suns were to burst forth at once in the sky, that would be like the splendor of the Mighty One.
Have sincere love for God, hanker after God alone, then say whether or not you can see Him.
