Man needs to

Jai Sri Ganesha,
Man cannot afford to be selfish beyond a limit,

Man cannot be unconcerned with sufferings of others,

Man kill other beings to gratify the palate on the path of taste,

If not directly man cannot afford to make butcher to act on behalf of,

Happiness of a man cannot be based on suffering of other beings,

It is true that what one sow, so shall one reap

Man needs to be responsible enough to adore non-violence,

If possible-man needs to be vegetarian for many reasons which involves health, humane, economic, ethical or ecological chapters,

Man needs to realize truth behind it that if man pains someone, invite pain for self perhaps may be in different form or at varying location,

Man needs be wakeful even when not in sleep.

May Lord bless all,

thanks Please
