Evil is an illusion. It appears to be very real to us, but that is the point of an illusion. Evil appears to exist so we buy into the illusion of the world, fear binds the world and love sets it free.
Most of what we call evil is a fear of dying, a fear of losing our bodies, but the thought came to me the other day in meditation, "If you aren't really here, how can you die here?"
To undo the evil of the world, look past it to what is commonly referred to as the Kingdom as that is real and the evil isn't. The Kingdom is all around us but we don't see it, mostly because on some level, we prefer the illusion.
Eventually, we will all go home together, and in fact this has already happened.
To quote Einstein:
A human being is a part of the whole, called by us, "Universe," a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest -- a kind of optical delusion of his consciousness.
This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest to us. Our task must be to free ourselves from this prison by widening our circle of compassion to embrace all living creatures and the whole of nature in its beauty.
Nobody is able to achieve this completely, but the striving for such achievement is in itself a part of the liberation and a foundation for inner security.
This isn't to say we shouldn't have laws and we shouldn't punish people who appear to break the laws, or people who appear to violate the life and liberty of others, but the first step to undoing an illusion is to recognize it is an illusion. And the thing about judging people and things as evil is it makes it possible to stop thinking and just put everything into the "evil" box and never really examine the illusion. Undoing the illusion is done at the level of the mind, not the level of the physical since the physical was created at the level of the mind.
To quote Einstein again:
No problem can be solved from the same level of consciousness that created it.
Which explains why almost every political "solution" is doomed to fail from the start.
