When referring to his disciples, The Master of Life and Truth prayed, “I pray not that Thou should take them out of the world, but that Thou should keep them from the evil one.” (the ego?) ~ John 17:15
From passages such as the above, we can conclude that there is an evil one in the world that has to be reckoned with. In the book of Genesis the evil one is the serpent who beguiles mankind to eat the forbidden fruit. In the New Testament he is the devil who tempts Jesus to reject God and worship him. (Matthew 4:1-10)
In the teachings of master Eckhart Tolle the evil one is the ego. But can we obliterate the ego and still accomplish anything positive, good and necessary in the world? The answer is an unequivocal yes. We will see how the ego becomes the servant of the Higher Truer Self.
