Yudhishthir asked - "O grandsire, tell me what foods are clean and unclean, what gifts are praiseworthy, and who are considered deserving and undeserving candidates for gifts?"
Vyaas Jee said - "A discourse between Rishi and Manu, the Lord of Creation, may be cited in regard to this question. Once in Sat Yug, Rishi asked Manu to tell them "What food should be taken, who is to be regarded a deserving person for gifts, what gifts should be made, how a person should study, what penances should one perform and how, what acts should be done and what act should not be done." Manu said - "In the regions which are normal, one can do silent recitation of sacred Mantra, fasts, knowledge of self, taking bathe in the waters in which precious stones have been dipped, taking holy butter, to cleanse himself speedily. If a proud man wishes for a long life then he should drink hot water for three nights. Refusal to which is not given and a gift, study of scriptures, penance, not injuring anybody, not being angry, worship of Devtaa - come under virtue. But at the same time a virtue may be a sin according to the time and space. Thus taking others things, injury and killing others may be virtue under special circumstances.

The bull, little ants, worms born in dirt, and poison should not be eaten by Braahman. They should not also eat fish without scales, four-footed aquatic animals (such as frogs - except the tortoise). Water fowls, ducks, cranes, shags, vultures, hawks, owls, four-footed carnivorous animals, birds, animals with two and teeth; milk of sheep, she-ass, she-camel, newly-calved cow, woman and deer should not be taken by Braahman.

There are two types of acts - virtuous and sinful. From worldly and Vedic point of view the virtue and sin are good and bad according to their results. From the Vedic point of view a virtue and sin, everything a man does or doesn't do, are classed under action and inaction. Inaction (not doing anything) leads to emancipation (Mukti); while the action (practice of Vedic rites) leads to repeated cycles of birth and death. From worldly point of view, sins lead to bad consequences while good actions lead to good results. Thus from worldly point of view all god or bad actions should be judged by their good or bad results. Any apparent evil action done for Devtaa, scriptures, life itself, and the means by which life is sustained produce good results. If any action produces bad results, expectedly or unexpectedly, should be punished. If any action is done to please or displease the mind, its sin should be cleansed by taking holy food and recitation of Mantra.

A king who doesn't do justice should fast for one night. A priest who doesn't counsel king properly should keep fast for three days. There are no repent for those who do not follow the duties according to their class and order, country and family.

Gifts should be made only to those who possess the knowledge of Ved. An improper gift and an improper acceptance produce evil results for both the giver and the acceptor. One may give to a person who is afflicted, ill, or poor. As a kernel without grains, as a well without water, as a libation poured on ashes, in the same way the gift is for a Braahman who is not learned."

Yudhishthir said - "I wish to know about the duties of kings and the four orders. How I should tread the path of morality? The practice of virtue and discharging the kingly duties are always  inconsistent with each other. How to reconcile them both?" Vyaas Jee, looking at Naarad Jee, said to him - "If you wish to know all this, then ask this from Bheeshm. He is well versed in the matter of duties, he will remove all your doubts about them. He has got this knowledge directly from Brihaspati, knowledge of Ved and their branches from Vashishth and Maharshi Chyavan of Bhrigu family, truths of mental and spiritual science from the eldest son of Brahmaa Jee - Sanat Kumaar, duties of all Yati from Maarkandeya, he obtained all weapons from Parashuraam and Indra. Although he is born as a human being, still hid death is under his control. There is nothing unknown to him which is known to anybody. He can duly discourse on duty and morality. Go to him before he takes his last breath."

Yudhishthir asked - I am his culprit as I have felled him by deceit while he was always fighting fairly, then how can I ask him about about morality?" Vaishampayan Jee says - "Hearing this Vaasudev said - "You should not behave like this in grief, do whatever Vyaas says. Your brothers, Braahman, remaining kings will go with you." Yudhishthir understood what he had to do, so he rose and keeping Dhritraashtra at the head of the train worshipped thousands of Braahman ascended a new chariot yoked with 16 bullocks, Bheem took the reins, Arjun held the umbrella over his head, Nakul and Sahadev took two yak-tails to fan him. Yuyutsu followed him in his chariot. Krishn with Saatyaki followed Kuru. Dhritraashtra along with Gaandhaaree was in the front in a palanquin. All other women, including Kuntee and Krishnaa, also headed behind Vidur. All entered the city through its well adorned gates.

Vaishampaayan Jee says - "They all entered the city. Everybody was praising Paandav and Draupadee. Yudhishthir entered the palace and worshipped his household Devtaa (Kul Devtaa). Then he came out and found Braahman with auspicious articles. Among them was a Raakshas named Charvaak in disguise of Braahman. He said - "On behalf of these Braahman I say that you are a wicked king, fie on you. After killing your elders and preceptor you should have died." Hearing this all Braahman got agitated with shame. Yudhishthir said - "There is no need to cry on me, I will just lay own my life." Braahman said loudly - "These are not our words." Then they recognized him as Raakshas Charvaak with their Divine sight and said - "This is Charvaak Raakshas, Duryodhan's friend. We have not said anything like this. Be prosperity to you all." Then they uttered "Hun" and by that sound only killed him then and there. Yudhishthir got very happy to see this."

Vaishampaayan Jee further siad - "Krishn said - "Braahman have always been the object of worship for me. They are like Devtaa on this Earth. Formerly in Sat Yug, there was a Raakshas named Charvaak who did a severe penance for many years in Badaree Van. Braahman repeatedly asked him to ask for a boon. At last he asked the immunity from fear from every being on earth. They gave him this immunity but to be careful while behaving with Braahman. Then he started giving pain to Devtaa so they went to Vishnu, Vishnu said, "I have already made the arrangements as how he will be killed. There will be a king Duryodhan in Dwaapar Yug, he will be his friend, and in his love he will insult Braahman. Braahman will kill him, so do not grieve for him. Protect your people and worship Braahman."
