Hindu scriptures give permission to have non-veg
a. There are many Hindus who are strictly vegetarian. They think that it is against their religion to consume non-vegetarian food. In fact the Hindu scriptures permit a person to have meat. The scriptures mention Hindu sages and saints consuming non-vegetarian foods.
b. It is mentioned in Ayodhya Khandam, verses 20,26 and 94 that when Rama was sent for Banavas he told his mother that he would have to sacrifice his tasty meat dishes. If Rama had to sacrifice his tasty meat dishes it meant that Rama had likeness for meat.
If Rama can have meat, why can’t the Hindus have meat?
Beef Eating in Hindu scriptures
.......Mahabharata Anushashan Parva chapter 88 narrates the discussion between Dharmaraj Yudhishthira and Pitamah Bhishma about what food one should offer to Pitris (ancestors) during the Shraddha (ceremony of dead) to keep them satisfied. Paragraph reads as follows:
"Yudhishthira said, "O thou of great puissance, tell me what that object is which, if dedicated to the Pitiris (dead ancestors), become inexhaustible! What Havi, again, (if offered) lasts for all time?
What, indeed, is that which (if presented) becomes eternal?"
"Bhishma said, "Listen to me, O Yudhishthira, what those Havis are which persons conversant with the rituals of the Shraddha (the ceremony of dead) regard as suitable in view of Shraddha and what the fruits are that attach to each.
With sesame seeds and rice and barely and Masha and water and roots and fruits, if given at Shraddhas, the pitris, O king, remain gratified for the period of a month.
With fishes offered at Shraddhas, the pitris remain gratified for a period of two months.
With the mutton they remain gratified for three months and with the hare for four months, with the flesh of the goat for five months, with the bacon (meat of pig) for six months, and with the flesh of birds for seven. With venison obtained from those deer that are called Prishata, they remaingratified for eight months, and with that obtained from the Ruru for nine months, and with the meat of Gavaya for ten months, With the meat of the bufffalo their gratification lasts for eleven months. With beef presented at the Shraddha, their gratification, it is said , lasts for a full year. Payasa mixed with ghee is as much acceptable to the pitris as beef. With the meat of Vadhrinasa (a large bull) the gratification of pitris lasts for twelve years
The flesh of rhinoceros, offered to the pitris on anniversaries of the lunar days on which they died, becomes inexhaustible.
The potherb called Kalaska, the petals of kanchana flower, and meat of (red) goat also, thus offered, prove inexhaustible.
So but natural if you want to keep your ancestors satisfied forever, you should serve them the meat of red goat.
