Even the Buddha ate meat. In buddhism it is a matter of not selfishly picking and choosing, but eating what is placed before you. It is attitude that matters. A lot of staunch vegetarians and committed believers in kale are egocentric people who pride themselves on their sacrifices and secretly wish to live forever, young and beautiful. That kind of motivation is the furthest possible away from being spiritual. It in fact fosters an over-blown ego which is exactly what spirituality needs diminished in order to flourish.
It seems that spiritual development tends to adapt to its environment and in the West, in Capitalism, where profit rules, spirituality is measured by how much profit can be made on it's outer trappings. So we have people eating kale instead of becoming humble. After all they don't want to hurt animals. And yet they do nothing to protest how farming corporations are treating these animals by keeping them all their lives in tiny enclosures with no fresh air or movement. Because supposedly spiritual people are not political. What a pathetic excuse and self-centred attitude. I won't disturb my white and pure energy field by thinking about these atrocities, they rationalize. In fact it is the spiritual people who are contributing to these atrocities continually without limit, by closing their eyes on their world and focussing on their naval.
Spiritual people in the West eat kale and won't get their hands dirty, like helping the homeless, never mind the animals and they think they will go to heaven or be saved just because they are happy and undisturbed. Ridiculous, because you can only become truly a spiritual person when you are so disturbed by the state of affairs in the world that you want to cry and do something about it, contribute to a humane way of living, which means helping the homeless, AND not eating kale. God, I think does not give two hoots about what you eat, but only about what kind of compassionate person you are.
