Illusions have to be forgiven at the level on which they seemingly occur. That’s why enlightenment cannot be postponed to some kind of afterlife. It has to happen while one is still being tempted to judge appearances as real. The mind cannot let go of illusions to which it’s not being exposed.
In illusions it takes two to tango, because illusions do not belong to reality but to the dualist thought of separation. First, there’s an illusory level of mind outside time and space which is projecting the universe, including the appearances of bodies in sickness and health. This takes no time at all. Second, there’s a ‘personal’ level where everything in this universe is being interpretated as either real or unreal. The first level of the dreaming mind usually is not under our direct control as ‘human’ beings but the second has a free choice for either judgment or forgiveness. To judge means to take the illusion of separation for real; to forgive means to overlook that and to take only the Kingdom of Heaven for real. Through forgiveness also the illusory division of mind levels is made undone. Forgiveness proves the willingness of the sleeping mind to awaken. The dreamer cannot awaken himself but without his willingness on the level of interpretation awakening wouldn’t happen at all.
This makes the level of interpretation, our ‘human’ existence, crucial to whether enlightenment occurs or not – enlightenment being the complete removal of all impediments to the Realization of Heaven, Pure Oneness, God.
