There is one sure way to develop your ego: refuse love. Yes, it is really that simple.
As one matures spiritually and looks back upon one's life, it readily becomes apparent that the simple refusal of love was the simplest, the most expedient way to juice the ego, to bolster it, to make it real.
But, of course, as the years go by one sees all the times love was offered and refused. And what was the purpose of that refusal? Who did you put down in that refusal? Who did you aggrandize? Yourself of course.
The simple practice of observing yourself throughout the day as you refuse love can really open one's eyes. For we are surrounded by love, and only in refusing to see can we avoid it.
So what shall it be today? Love or ego?
