Sin

Yudhistira to Arjuna:

A perpetrated sin is expiated

1. by auspicious acts, 
2. by publishing it wildly, 
3. by repentance, 
4. by alms-giving, 
5. by penances, 
6. by trips to tirthas after renunciation of everything, 
7. by constant meditation on the scriptures. 

Of all these, he that has practised renunciation is believed to be incapable of committing sins anew. The Srutis declare that he that practises renunciation

1. escapes from birth and death, and 
2. obtaining the right rood, that person of fixed soul attains to Brahma. 

I shall, therefore, O Dhananjaya, go to the woods, with your leave, O scorcher of foes,

1. disregarding all the pairs of opposites, 
2. adopting the vow of taciturnity, and 
3. walking in the way pointed out by knowledge. 

O slayer of foes, the Srutis declare it and I myself have seen it with my eyes, that one who is wedded to this earth can never obtain every kind Of religious merit. Desirous of obtaining the things of this earth, I have committed sin, through which, as the Srutis declare, birth and death are brought about. Abandoning the whole of my kingdom, therefore, and the things of this earth, I shall go to the woods,

1. escaping from the ties of the world, 
2. freed from grief, and 
3. without affection for anything. 

Do thou govern this earth, on which peace has been restored, and which has been divested of all its thorns. O best of Kuru's race, I have no need for kingdom or for pleasure.' Having said these words, king Yudhishthira the just stopped.
