So much of people's behavior is shaped by fear and they don't even know it. Both physically if a person is a meat-eater - and psychologically with things like fear of others' opinions, and all the fears that thought creates within the field of time (if closely examined we see psychological fears are all in time – about the future or about the past - and are made by thinking about things thought was not made for...).
Most people live in fear but don't know it - it runs their behavior - especially meat eaters - the fear is in the body b/c when animal died it was afraid - when people live w/ something so much they don't know they have it...
One of the key things meat eaters don't realize is that their bodies are always in a state of mild fear but they get used to it so it's not noticeable -- that's the fear that comes through the meat because when the animal is killed it's afraid. And, all the talk about compassionate killing is utter nonsense. Come here sweetie, and zap. There's no such thing as compassionate killing.
Some fears are practical, some in the body, and most, a result of over thinking, in the field of time… worry about the past or the future.
Thought is time - psychologically - and being so, it breeds fear. If you see this in daily life - if thought sees the fact that in operating within time, it gets itself bound up in fear - it ceases to do so.
It is really great to live without fear. Physical fear for survival, e.g. of a dog, is natural. But that translates into our psyche and we try to protect the "self" which is like a bubble anyway, made out of memories. I believe it's impossible to live fully without fear as long as one eats animals (see article on diet). Psychological fear is usually based on thought and time. Thought needs to see its own limitation and that understanding brings change.
