“In the regeneration and divinisation of man, the first step is to eliminate his beastly nature. The predominant trait in beasts is cruelty. Therefore, wise sages prescribe Ahimsa (non-injury). This is the most effective master-method to counteract and eradicate completely the brutal, cruel Pasu-Svabhava (bestial nature) in man.
Practice of Ahimsa develops love. Ahimsa is another name for truth or love. Ahimsa is universal love. It is pure love. It is divine Prem. Where there is love, there you will find Ahimsa. Where there is Ahimsa, there you will find love and selfless service. They all go together.
The one message of all saints and prophets of all times and climes, is the message of love, of Ahimsa, of selfless service. Ahimsa is the noblest and best of traits that are found expressed in the daily life and activities of perfected souls. Ahimsa is the one means, not only to attain Salvation, but also to enjoy uninterrupted peace and bliss. Man attains peace by injuring no living creature.
Ahimsa or non-injury, of course, implies non-killing. But non-injury is not merely non-killing. In its comprehensive meaning, Ahimsa or non-injury means entire abstinence from causing any pain or harm whatsoever to any living creature, either by thought, word, or deed. Non-injury requires a harmless mind, mouth, and hand.
Ahimsa is not mere negative non-injury. It is positive, cosmic love. It is the development of a mental attitude in which hatred is replaced by love. Ahimsa is true sacrifice. Ahimsa is forgiveness. Ahimsa is Sakti (power). Ahimsa is true strength.”
