Today "aged" foods like sauerkraut, miso, and tempeh are fermented in hygienically sanitized stainless-steel vats to assure cleanliness, so we can no longer be sure they will provide us with the B12 we need. Vegans should not mess around with this issue.

Inspiration pushes me out of my tight intellectual comfort zone and into humility, the wonderous state of not knowing. From this place of zero, limitless possibilities seem to arise.

It is true that every being is enjoying life or suffering as a direct result of his or her own past actions. The animals in the factory farms may have been meat-eating human beings in a previous birth; we don't know, and it is not our place to judge.

In fact, studies show that vegans tend to get more iron than meat eaters. Vitamin C from fruits and vegetables increases iron absorption. Meanwhile, dairy products reduce iron absorption significantly.

Through yoga practice you can change the course of your life by purifying your karma. But to do that you must have an idea of where you've been and where you want to go.

Raising crops to feed animals for human consumption requires a lot of land. It takes eight or nine cows a year to feed one average meat eater; each cow eats one acre of green plants, soybeans and corn per year; so it takes eight or nine acres of plants a year to feed one meat eater, compared with only half an acre to feed one vegetarian.

One's knowledge of karma should not be used to judge others. You should ask yourself: Do I like where I am going, or do I want to change my direction?
