Our lives are filled with turning points that can steer us in different directions. To have found the Dharma and be facing in the direction of greater consciousness is extraordinarily good karma that can powerfully fuel and inspire our practice with sincerity and gratitude.
The only thing that we can know for sure is the constancy of chance. It's the most basic fact of our existence. Realization of the truth of impermanence is a gateway out of feeling the separateness - the suffering of self-centered existence. We begin to understand that we are intimately woven into endlessly changing, reflective web of life.
