There is a Sufi tale.
Becoming angry with his prime minister, a king confined prime minister in a very high tower with no way to escape. If he tried to jump he would surely be killed. The king did not know it, but on his way to the tower the prime minister had whispered something in his wife’s ear. On the very first night she came and left an ordinary insect on the tower wall. She applied a little honey to its antennae. The insect began to climb up the tower in search of the honey, but she had also tied a thin silk thread to its tail.
Slowly the insect climbed the three hundred feet of the tower where the minister was waiting for it. He grabbed at the silk thread to which the wife had tied a string. And to the string she had tied a cord, and attached to the cord was a strong rope. The minister pulled till he had the rope in hand, and with its help he climbed down from the tower. The story states that not only did the minister escape the prison, but he also discovered the means to escape from life’s ultimate prison.
If even the thinnest, weakest thread comes to hand, there is no difficulty in attaining liberation. The weakest thread can pave the way to beatitude, but the thread must come to hand. A slight ray, once recognized, can lead to the sun. All religions, all gurus, have reached God by catching hold of one thin thread or other. These threads are many, and can be tied to many kinds of insect. It isn’t necessary to smear the insect’s antennae with honey; you can apply anything that tempts the insect to climb to the prisoner. The thread becomes the bridge.
