Thread

There's a thread you follow. It goes among things that change. But it doesn't change. People wonder about what you are pursuing. You have to explain about the thread. But it is hard for others to see. While you hold it you can't get lost. Tragedies happen; people get hurt or die; and you suffer and get old. Nothing you do can stop time's unfolding. You don't ever let go of the thread.

Rigpa

"The mind of clear light (rigpa) is also called "all-empty" because it is beyond the entire scope of conceptual consciousness. Even while you are still seeming to be a sentient being and despite the generation of a great many good and bad conceptions such as manifest desire, hatred, and bewilderment, the diamond mind itself is free from the pollutions of these defilements." 

Fyodor

Tolstoy
