Meaning of life, to treat all humans and animals with love, compassion and nonviolence

To live a life of love, compassion and nonviolence to everyone.
To live after the principle ' “all breathing, existing, living, sentient creatures should not be slain, nor treated with violence, nor abused, nor tormented, nor driven away.” '

To fight against all discrimination and violence against all beings on this planet, all humans and all other animals:
"We do not object to speciesism in a vacuum. We reject it because it is like other forms of discrimination. What all forms of discrimination share in common is the use of an irrelevant criterion to exclude people from full membership in the moral community. Racists devalue those of different races based solely on skin color; sexists devalue women solely because of sex and gender; heterosexists deny full membership in the moral community to gays, lesbians, transgenders, etc. simply on the basis of sexual orientation. Speciesists deny full membership in the moral community based solely on species.

All of these forms of discrimination are morally unjustifiable. We reject speciesism because it is indistinguishable from these other forms of discrimination."
