The eating of meat is certainly impure. Vegetarian food is definitely pure. Whose goal is directed only towards Dharma, they will do well with vegetarian food. And those who are working for advancement in this world, it is true that meat can be of benefit to them.
It is also true that pure food gives rise to pure thoughts. If one wants to become a devotee, then meat should be renounced. This is because it makes excitement. And then its nature is impure. It is not proper for us to take another life for our personal enjoyment.
Just as long as warrior energy remains foremost in man, for so long meat will remain a regular food commodity. By eating animals man gets an animalistic nature, and thus brings about the destruction of the race.
When a man acts without selfishness, then lust and greed are completely without energy, and one renounces self-conceit. Without knowledge of ego, Sattwa guna is expressed. These are the signs that an individual has no desire for consuming meat.
