The less you love yourself, the more likely it is that you will be a flesh eater. And the more you love yourself, the more you know your welfare. The more determined you are to help yourself out of this mess, the more loving and more compassionate you will be towards all conscious beings.
All kinds of cruelty come from the same source. Be it rape, be it debauchery, be it environmental damage, or be it flesh consumption or dairy consumption, all of them are co-related. They all have a central root, which is lack of love, which is lack of awareness, which is a lot of ignorance. Spirituality is the only solution.
