In spiritual circles there’s much ado about overcoming illusion.
In Hinduism and Buddhism, Maya is illusion and ignorance. Like dirt being removed from an object to reveal its true nature, dispelling illusion reveals truth.
In Zen, the confrontation with reality known as kenshō is the goal you cannot reach by striving. As Brad Warner would say, to get started you should first “Sit down and shut up.”
In Christianity, nepsis (watchfulness) and diakrisis (discernment) cleanse the nous (the ‘true I’) and dispel illusion, allowing entrance to the Kingdom of God.
Luke 17:20-21 (King James Version).
And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.
