Mahabharata Anushasna Parva Chapter 142:3

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 142:3 That man who conducts himself with sincerity becomes endued with Righteousness. The man who is always devoted to sincerity of behaviour, succeeds in attaining to a residence among the deities. Hence, he who wishes to achieve the merit of righteousness should become endued with sincerity. Possessed of a forgiving disposition and of self-restraint, and with wrath under complete subjection, one should transform oneself into an embodiment of Righteousness and become freed from malice. Such a man, who becomes devoted, besides, to the discharge of all the duties of Religion, becomes endued with the merit of Righteousness. Freed from drowsiness and procrastination, the pious person, who adheres to the path of Righteousness to the best of his power, and becomes possessed of pure conduct, and who is venerable in years, comes to be regarded as equal to Brahma himself." 'Uma said, "By what course of duties, O god, do those ascetics who are attached to their respective retreats and possessed of wealth of penances, succeed in becoming endued with great splendour? By what acts again, do kings and princes who are possessed of great wealth, and others who are destitute of wealth, succeed in obtaining high rewards? By what acts, O god, do denizens of the forest succeed in attaining to that place which is eternal and in adorning their persons with celestial sandal-paste? O illustrious god of three eyes, O destroyer of the triple city, do thou dispel this doubt of mine connected with the auspicious subject of the observance of penances by telling everything in detail." 'The illustrious deity said, "Those who observe the vows relating to fasts and restrain their senses, who abstain from injury of any kind to any creature, and who practise truthfulness of speech, attain to success and ascending to Heaven sport in felicity with the Gandharvas as their companions, freed from every kind of evil. The righteous-souled man who lies down in the attitude which appertains to Manduka-Yoga, and who properly and according to the ordinance performs meritorious acts after having taken the Diksha, sports in felicity in the next world in the company of the Nagas. That man who lives in the company of deer and subsists upon such grass and vegetables as fall off from their mouths, and who has undergone the Diksha and attends to the duties attached to it, succeeds in attaining to Amaravati (the mansions of Indra). That man who subsists upon the moss he gathers and the fallen leaves of trees that he picks up, and endures all the severities of cold, attains to very high place. That man who subsists upon either air or water, or fruits and roots, attains in after life to the affluence that belongs to the Yakshas and sports in felicity in the company of diverse tribes of Apsaras. Having practised for two and ten years, according to the rites laid down in the ordinances, the vow relating to the endurance of the five fires in the summer season, one becomes in one's next life a king.
