This is from the words of Jesus in the Gospel of Luke: And to all he said,
“If anyone wishes to be a follower of mine, he must leave self behind; day after day he must take up his cross and come with me. Whoever cares for his own safety is lost; but if a man will let himself be lost for my sake, that man is saved. What will a man gain by winning the whole world, at the cost of his true self?” (Luke 9:23-26)
The great hindrance to this journey, this following of Christ, is the way in which we falsely identify ourselves with our ego. Perhaps we as religious people take it a little too much for granted that it is a good thing to leave self behind. I was once talking to a rather successful business-woman in New York who came to a talk I was giving there. I gave this talk on leaving ego behind, which you wouldn’t think anyone could really object to. She came up afterwards and said, “What nonsense you are talking! I don’t want to leave my ego behind.” She said, “I am my ego.” At least I think she had a clear sense of what she believed. We, most of us, identify ourselves with our ego, unconsciously.
