Impersonalism is only a solace for the frustrated. When we are frustrated by the relative personalism of this material world, we try to find out, in material way, the opposite number. Just like a patient who is suffering in diseased condition tries to find out something opposite number. So this is a long course explanation, but actually impersonalism cannot give us the answer to our eternal search after peace. So far we are convinced from the Vedic literatures, God is a Person exactly like you are a person, I am a person, but His personality is very great, full with six opulences, and none of the living entities beginning from the highest like Lord Brahma down to the ant, nobody can be on the equal level with God. These things are all explained in our books, and I would request you to read these books especially the recently published Isopanisad.
