When human body itself is made of flesh, where is the need to consume the flesh of birds and animals? You should partake of only sacred food. Only then you will have sacred feelings.
From the time of our birth till the time this body perishes, we are making many attempts to earn money and acquire food. In this process of amassing wealth, we are adopting means and methods which are adopted also by the birds and animals.
In the matter of acquiring food, different kinds of strength, abilities and skills are used by us but these very same skills are used by animals and birds as well.
