In the relative world, outer phenomena are constantly changing, our inner mind is constantly changing, and therefore our perceptions are constantly changing. We can see that everything is transitory, including ourselves. But the self, or ego, would like us to believe that everything is permanent. If we actually admitted that everything is transitory, we would have no solid ground for attachment —and ego is based on attachment.
Grasping to a nonexistent self, we misread our world and lose the true treasure of our mind. Because of our belief in a self that must be preserved at all costs, ego controls our every mental, emotional, verbal, and physical act. Although our wisdom mind is completely radiant at all times, we become like a homeless prince: a monarch who lives like a vagabond, unaware of his own inheritance.
