Non violence means being free of any such violence

Purport:-
The Supreme Lord her says that one should worship The demigods and the deities selflessly. He has told that worshipping demigods is important as pleased by the worship , they bestow best fruits upon us . But one has to give up all his pride and become extremely humble while worshipping. Following the rites., and rituals and correct procedure of worship one loses his ego and his life becomes disciplined.
Lord krishna says that brahmins and gurus (those who teach us ) ie- our elders, spiritual masters, guides, and those who are superior to or older than us should all be revered and worshipped. we should try to please them in all possible ways.
Besides, the body should be kept clean and pure. Purity of body leads to purity of conscience. When we try to keep the body clean and pure , we note that this body is a 'bowl of filth'. There is nothing in it which is clean, pure, clear or fragrant. Such thoughts cut away all the bonds of attachment with this body and destory our false ego.
Simplicity is yet another part of austerity of body. One should give up all his haughtiness and vanity, and become humble and polile so that his entire behaviour- walking, talking, the way of holding body, looking, eating and drinking all become simple and straight. Well-being of a devotee lies in this alone. Praticing celebacy is also essential for him. He should observe the rules laid down by the scriptures regarding sexual relations (Which are different for different Ashrams). He should keep his thoughts pure and with firm will avoid being attracted towards any woman other than his wife.
Besides all these-practising non-violence also comes under this kind of austerity. Our ignorance and passions like lust, desire, anger, attachments and greed lie in the root of all violence. Enslaved by these, man hurts and incurs loss upon others. He kills animals for meat and leather. To fulfill his own desire he hurts others. Non violence means being free of any such violence.
Worshipping demigods and spiritiual masters, cleanliness, simplicity, celebacy and non-violence. These are five types of ansterties of body. The most important thing about these is that one does not have to undergo any tough penance, he just has to 'renounce'. While 'worshipping he has to renounce his pride and vanity' in 'cleanliness'- he gives up idleness, in 'simplicity'- ego and haughtiness, in 'celebacy'- his physical pleasure and in 'non-violence' he has to renounce the desire if having happiness, so has the Lord described the austerity of body.
