The Hindu doctrine of Ahimsa (Non Violence) is a comprehensive term and emphasises the value of Satya (Truth) Tyaga (Non-Covetousness) and Brahmacharya (Self-restraint).
"Meat diet is prohibited. Do not kill even for sacrifice (Yajna)".
This is the teaching of the Hindu sages. The Statesman sage of Mahabharata, Bhishma censures animal slaughter even for sacrifice (Yajna).
The mighty faith of Mahavira, the prophet of Jainism reproclaimed the truth of the ancient Vedic Rishis.
Over and over again he taught 'regard every living being as thy own self and harm no one'.
In his last sermon given on the last day of his earthly life Mahavira said "Destroy the bondage of Karma. Be kind to every creature" 'O Man!', he said "Thou art thine own friend".
Yes-Man is his own friend, he also is his own enemy.
For there is the great cosmic law that what you do comes back to you. What you do unto others, you do unto yourselves. Therefore be kind to all, if you want to be really happy.
