For such offences as cutting down fruit-trees or grasses, or killing insects, or injuring sentient creatures, the penance is to repeat so many texts of the Veda, to eat clarified butter, or to stop the breath. A low-born man who treats a Brahman disrespectfully, or who even overcomes him in argument, must fast all day and fall prostrate before him. He who strikes a Brahman shall remain in hell a thousand years. Great, however, is the power of sincere devotion. By repentance, open confession, reading the Scripture, almsgiving, and reformation, one is released from guilt. Devotion, it is said, is equal to the performance of all duties; and even the souls of worms and insects and vegetables attain heaven by the power of devotion. But especially great is the sanctifying influence of the Vedas. He who can repeat the whole of the Rig-Veda would be free from guilt, even if he had killed the inhabitants of the three worlds. The last book of Manu is on transmigration and final beatitude. The principle is here laid down that every human action, word, and thought bears its appropriate fruit, good or evil. Out of the heart proceed three sins of thought, four sins of the tongue, and three of the body, namely, covetous, disobedient, and atheistic thoughts; scurrilous, false, frivolous, and unkind words; and actions of theft, bodily injury, and licentiousness. He who controls his thoughts, words, and actions is called a triple commander. There are three qualities of the soul, giving it a tendency to goodness, to passion, and to darkness. The first leads to knowledge, the second to desire, the third to sensuality. To the first belong study of Scripture, devotion, purity, self-command, and obedience. From the second proceed hypocritical actions, anxiety, disobedience, and self-indulgence. The third produces avarice, atheism, indolence, and every act which a man is ashamed of doing. The object of the first quality is virtue; of the second, worldly success; of the third, pleasure. The souls in which the first quality is supreme rise after death to the condition of deities; those in whom the second rules pass into the bodies of other men; while those under the dominion of the third become beasts and vegetables. Manu proceeds to expound, in great detail, this law of transmigration. For great sins one is condemned to pass a great many times into the bodies of dogs, insects, spiders, snakes, or grasses. The change has relation to the crime: thus, he who steals grain shall be born a rat; he who steals meat, a vulture; those who indulge in forbidden pleasures of the senses shall have their senses made acute to endure intense pain.
