There is a Sufi story that Mulla Nasruddin wanted to learn swimming. But as he went close to the river with the teacher who was going to teach him, he slipped and fell into the river -- and it was a deep river. He was saved by the teacher, but he went a few times under the water; and as he was taken out, he took his shoes and ran away.
The teacher said, "Where are you going? You have come to learn swimming."He said, "Now, first I will learn swimming and then I will come near the water; otherwise I am not going to come near the water -- it is too dangerous. First I will learn swimming." But where is he going to learn swimming? You cannot learn swimming in your bedroom. There is no other way... but unfortunately he entered the river from the wrong end. The teacher would have taken him to where the water was shallow, and slowly would have encouraged him to go towards deeper waters. As he would have become more proficient, the teacher would have encouraged him to go farther and farther.
Just a little trust is enough.
In the beginning you cannot hope to have total trust. That's how we start making impossible demands upon ourselves, and then we cannot fulfill them. Guilt arises, a condemnation of oneself arises, a rejection: "I am not worthy...." But all these things are unnecessary.
And this has happened all over the world. Everybody is feeling unworthy because he aspired in the very beginning to find the end. Naturally it was impossible -- he could not reach it -- and that stopped him even starting the journey again.
