Mbh 13.117.6a

"'"The worm said, 'A living creature, in whatever situation he may be placed, becomes attached to it. In even this order of being I am happy, I think, O thou of great wisdom! It is for this that I wish to live. In even this condition, every object of enjoyment exists for me according to the needs of my body. Human beings and those creatures that spring from immobile objects have different enjoyments. In my former life I was a human being. O puissant one, I was a Sudra possessed of great wealth. I was not devoted to the Brahmanas. I was cruel, vile in conduct, and a usurer. I was harsh in speech. I regarded cunning as wisdom. I hated all creatures. Taking advantage of pretexts in compacts made between myself and others, I was always given to taking away what belonged to others. Without feeding servants and guests arrived at my house, I used to fill, when hungry, my own stomach, under the impulse of pride, covetous of good food. Greedy I was of wealth, I never dedicated, with faith and reverence, any food to the deities and the Pitris although duty required me to dedicate food unto them. Those men that came to me, moved by fear, for seeking my protection, I sent adrift without giving them any protection. I did not extend my protection to those that came to me with prayers for dispelling their fear. I used to feel unreasonable envy at seeing other people's wealth, and corn, and spouses held dear by them, and articles of drink, and good mansions. Beholding the happiness of others, I was filled with envy and I always wished them poverty. Following that course of conduct which promised to crown my own wishes with fruition, I sought to destroy the virtue, wealth, and pleasures of other people. In that past life of mine, I committed diverse deeds largely fraught with cruelty and such other passions. Recollecting those acts I am filled with repentance and grief even as one is filled with grief at the loss of one's dear son.
