Once upon a time a devotee of God came to a saint of the locality and went on denouncing worldly people and their ways of life. The saint said, “Have you seen a crab? The mother crab gives birth to hundreds of small crabs and lives in a hole with her children, but she has to go out in search of food. She comes out of the hole but must on account of the little ones go into the hole again. Having given birth to hundreds of children she has no energy or thought left for herself. Worldly people, similarly, having been engaged in various concerns, exhaust their minds. How can they pay attention to the realisation of God? If any of them makes an attempt, he is immediately overwhelmed by the demands of his worldly concerns and possessions. That is why it is difficult for worldly people to attain realisation of God.”
