Illusion about the true nature of existence is literally illusion about the nature of one's own life.

Illusion about the true nature of existence is literally illusion about the nature of one's own life. This is the fundamental source of all illusions. If we are ignorant about the nature of our own existence, then we will be ignorant about the nature of other people's lives, too. On the other hand, when our lives are free of illusion, we can perceive the treasure tower that shines resplendent in all people, in all beings.
