Is it created by the mind? Does being virtuous not lead to naturally successful outcomes?Humans "know" by contrast. It is impossible to have a concept of "good" without "evil". This dichotomy, this dualism is created by the mind. The universe is not divided until we see it that way. Then, when we take this for real, we wander through and endless maze of illusion, disoriented and confused because we can't make life fit into our dualistic hypnotic trance.
All the unanswerable questions about 'God' are a result of erroneous, childish concepts of what 'God' would be.
It is outcomes which tell us the difference between right and wrong and good and evil. It is not a human construct. It is a construct of nature.
