5.40.19

ātmā nadī bhārata puṇyatīrthā satyodakā dhṛtikūlā damormiḥ |
tasyāṃ snātaḥ pūyate puṇyakarmā puṇyo hyātmā nityamambho'mbha eva || 19 ||

Behold, illustrious and mighty kings, having ruled lands abounding with wealth and corn, have become the victims of the Universal Destroyer, leaving behind their kingdoms and vast sources of enjoyment. The son brought up with anxious care, when dead, is taken up and carried away by men [paragraph continues] (to the burning ground). With the dishevelled hair and crying piteously, they then cast the body into the funeral pyre, as if it were a piece of wood. Others enjoy the deceased's wealth, while birds and fire feast on the elements of his body. With two only he goeth to the other world, viz., his merits and his sins which keep him company. Throwing away the body, O sire, relatives, friends, and sons retrace their steps, like birds abandoning trees without blossoms and fruits. The person cast into the funeral pyre is followed only by his own acts. Therefore, should men carefully and gradually earn the merit of righteousness. In the world above this, and also in that below this, there are regions of great gloom and darkness. Know, O king, that those are regions where the senses of men are exceedingly afflicted. Oh, let not any of those places to thine. Carefully listening to these words, if thou canst act according to them, thou wilt obtain great fame in this world of men, and fear will not be thine here or hereafter. O Bharata, the soul is spoken of as a river; religious merit constitutes its sacred baths; truth, its water; self-control, its banks; kindness, its waves.

He that is righteous purifieth himself by a bath therein, for the soul is sacred, and the absence of desire is the highest merit. O king, life is a river whose waters are the five senses, and whose crocodiles and sharks are desire and anger. Making self-control thy raft, cross thou its eddies which are represented by repeated births! Worshipping and gratifying friends that are eminent in wisdom, virtue, learning, and years, he that asketh their advice about what he should do and should not do, is never misled. One should restrain one's lust and stomach by patience; one's hands and feet by one's eyes; one's eyes and ears by one's mind; and one's mind and words by one's acts. That Brahmana who never omitteth to perform his ablutions, who always weareth his sacred thread, who always attendeth to the study of the Vedas, who always avoideth food that is unclean, who telleth the truth and performeth acts in honour of his preceptor, never falleth off from the region of Brahma. Having studied the Vedas, poured libations into fire, performed sacrifices, protected subjects, sanctified his soul by drawing weapons for protecting kine and Brahmanas, and died on the field of battle, the Kshatriya attaineth to heaven. Having studied the Vedas, and distributed in proper time, his wealth among Brahmanas, Kshatriyas, and his own dependents, and inhaled the sanctified smoke of the three kinds of fires, the Vaisya enjoyeth heavenly bliss in the other world.
