Kural - 254

'What's grace, or lack of grace'? 'To kill' is this, that 'not to kill';
To eat dead flesh can never worthy end fulfil

Explanation
If it be asked what is kindness and what its opposite, the answer would be preservation and destruction of life; and therefore it is not right to feed on the flesh (obtained by taking away life).
