There is a story about Narada being born as a worm.
On the approach of a chariot the worm moved quickly away from its route lest its wheel should crush it to death.
The King seated in the chariot burst out into laughter at the above sight when the worm told him as follows:
-“There is nothing to be laughed at in my action. In every birth the body is much dear to the atman (soul). just as you love your body I also love and protect my body. (Mahabharata ).
