Brahmajala Sutta (Theravada)
In the second part, the Buddha explains the major beliefs of ascetics in India. He begins by saying, ""Monks, there are other things which are very deep (profound), very hard to understand, very difficult to perceive, so holy and sacred, unreached by means of mind, so subtle, that they are only to be understood and experienced by the wise. These things were perceived clearly, seen clearly and were discarded by the Tathagata, and by this act based on the truth that people praise and revered Tathagatha. What are those things?""
List of animal rights advocates
Historically speaking it could well be argued that the genesis of the Animal Rights movement was truly in India given the impact that both Buddhism and Jainism had on people in India and the neighbouring countries in Asia.
The largest number and highest percentage of Vegetarians per population for any country is in India. Buddhism among the global religions is an animal rights religion par excellence. It has long subscribed to the belief that all life forms including that of non-human animals are sacred and deserving of respect, and extolls kindness and compassion as utmost virtues worthy of cultivation. Buddhism unreservedly embraces all living beings in its ethical cosmology without discrimination on grounds of species, race, or creed. Buddhist tenets—including the first precept, “Do not kill”—extend to both human and non-human sentient beings. The Buddha was so adamant and protective of the more vulnerable members of the moral community—namely the animals—that he declared that: “He who has laid aside the cudgel that injures any creature whether moving or still, who neither slays nor causes to be slain—him I call an Arya (Noble person)” (Dhammapada).
