The mind is divided; our prayers are through that divided mind. There is a beautiful story from Puranas on the Great Lord Shiva.
Once it happened that a man was worshiping Shiva. He worshiped and worshiped, prayed and prayed for years. Then Shiva appeared and he said, ”You can ask for three blessings, three gifts; three boons can be given to you.” The man had been worshiping for so long that he really had forgotten why he had started. His mind was so constantly changing. The worship had become an obsession. He had forgotten for what, so he said, ”Let me think.” Then he asked for one gift. The gift was given. Then he became aware that this wouldn’t do; he had asked for something wrong. He was angry with his wife, so he had said, ”Kill her!” Immediately she was dead. And this can happen to any husband or any wife. They are fighting, filled with hate. But hate is also not total, there is love also. The mind is divided: you love the person and you hate the same person. It is always fifty-fifty. He asked that the wife should be killed, and the wife was dead; immediately she fell down. The moment she was dead he became aware that he loved her very much, so he said, ”Please, revive her again.” So the second gift was wasted. Two gifts wasted: first, she was killed, second, she was revived – only one was left. Then he said, ”Now, give me time enough to think; otherwise I will again make a mistake, and then there is no fourth.” Shiva waited and waited. Years passed and he would come again and again and he would ask, ”Now you ask for the third.”
The man was so puzzled he couldn’t sleep. He became almost insane just thinking about the one wish because only one was left. He went visiting all the persons he knew who were wise, and they suggested many things, but nothing seemed worthwhile. Then he asked Shiva himself. ”You tell me.I am going mad!”
And what Shiva told him is to be remembered. He said, ”There can be only one wish, one desire which is worthwhile. Ask for desirelessness, otherwise, nothing is worthwhile. Whatsoever you ask, the next moment you will want something else, even just the opposite of the first.”
