Evil has no actual existence, like a rock, a tree, or a bird.
Evil only “exists” in the minds of humans, in their thoughts, words and deeds.
Evil, as such, is indeed the absence of our proper relationship with reality.
Our proper relationship is participating with the one source of all. It is a part of each one of us. It is a participatory connected relationship.
We all know this intuitively, and either choose to participate in reality, or to push it away to maximize our selfish survival instincts.
Give me an example of evil, and every example will inevitably come from the concept in the mind of a human, or group of humans together, and the outgrowth of their actions, thoughts and words.
Why does the concept of evil exist in the minds of humans? Because we have a choice of living in the reality we have been placed in,or not.
When we live in the ruminative (vain imagination) part of our brain, it pulls us out of relationship with reality.
Thus, when a person says “There is no objective reality, only a subjective one” they are proving what is being said here.
Reality is Dharma
