There is a moment when you realize that you are going to have to die in reality, not just pretend to die. Not just read about dying, not just recite Rumi late at night, but really, day by day, hour by hour, moment by moment, go into the darkness of the Love of God and really surrender, a moment when you realize that to do that, you will need Divine courage.
The silent mind, cultivated in many different forms of meditation, is the matrix of intuition. When you are in touch with the stillpoint at the center of your being there is no need to use imagery or verbal exercises to activate intuition. It flows by itself, unimpeded by fears or preoccupations.
