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?

Compassion is essential for any type of relationship between anybody – human to human, human to dog, human to cat, human to bird.

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.

Many genetically "altered" fish escape from the confines of the crowded floating concentration camps to mingle and mate with their wild fish cousins, causing horrible and irreversible damage to wild species.

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.

Everything we do should contribute to happiness.

What we see in the world around us is just a reflection of what is inside of us.
