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.

If you practice Yoga for small, selfish reasons, you will remain the same, bound by your beliefs about what you can and cannot do. Let go and offer your effort to limitless potential. Dedicate yourself to the happiness of all beings.

The practices of Yoga will help you maintain equanimity in all situations by teaching you to become transparent, able to allow both joy and sorrow to flow through you without destroying your peace of mind.

Knowing the truth about the hell-realms that animals have to endure, it would be wise of us to do our best now not to plant the karmic seeds that would cause us to be reborn as an animal in one of those hell realms.

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.

In fact, we would know ourselves that we are not meant to be meat eaters, and we would not have allowed ourselves to become conditioned to meat eating in the first place, if the effects of meat eating were felt right away. But since heart disease, cancer, diabetes, osteoporosis, etc. usually take many years to develop, we are able to separate them from their cause (or contributing factors) and go on happily eating an animal-based diet.
