If we weren't so dirt-conscious, we would obtain adequate vitamin B12 from soil, air, water, and bacteria, but we meticulously wash and peel our vegetables now - and with good reason, as we can't be sure our soil is not contaminated with pesticides and herbicides.

What we do to others will come back to us. You can't expect to be happy by causing unhappiness to others.

Yoga teaches us that we can have whatever we may want in life if we are willing to provide it for others first.

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.

To live and breathe with an exclusive focus on one's small self, disconnected from the whole, is the definition of egotism.

As humans, we do get to choose what we eat, and when we choose to eat a plant, we are eating (i.e., harming) just that plant, plus indirectly whatever nutrients that plant consumed over its lifetime (and we are also harming whatever beings may have been living on that plant or who were injured or killed in the harvesting process). But when we eat an animal, we are eating not just that animal, but also indirectly all of the plants and other beings that that animal ate over its lifetime - those plants became the flesh that we eat.

How we treat others will determine how others treat us, and how others treat us will determine who we are.
