The following story is taken from Swami Muktananda's book, Kundalini: The Secret of Life. I've always liked it and I want to share it with you.
Before the creation of the world, only God existed. After some time, God became bored with being all alone and wanted somebody to play with. So God created the world from Himself and Herself and formed lesser gods to help operate the Universe. But the beings in God's creation knew they were divine, and they knew how to merge back into the source from which they came. Within a short time, they lost interest in the world, and all thronged back to God in heaven. God's game was ruined. God once again became bored.
God called a council of the other gods and asked them for their help. One suggested, "Why not throw everyone out of heaven, close the gates, and hide the key? And erect the veils of forgetfulness, so that these beings do not remember easily where they came from?"
God thought this was an excellent idea. "But where should we hide the key to heaven?" God asked.
"In the deepest depths of Pacific Ocean," suggested one god.
"How about the top of the Himalayas?" said another.
"No, no. Put it on the moon. It is so far, no one will ever reach it."
God sat in meditation to see the future. God appeared to be discouraged, saying, "None of these ideas will work. Humans will explore the far reaches of the Universe. Not only will they dive to the bottom of the ocean and climb the highest mountain, but they will visit the moon, explore the planets, and attempt to discover the workings of the cosmos."
The gods became silent. Suddenly God said, "I have the answer. I know the one place humans will never look for the key to Heaven. That place is within themselves, right in the core of their being. They'll travel millions of miles into space, but they will never take two steps within themselves to find the key to heaven."
The gods all applauded God's brilliant plan. And God has delighted in watching our search for the way home ever since.
