Prajna, a Buddhist term, originally refers to diamonds, and later refers to great wisdom, the wisdom of Buddha.
What is life?
Life is a constant confusion and progress.
No confusion can stop the progress of life, so why should we still be confused by all the unsolvable unknowns and knowns, and call out with that heart-breaking feeling?
Calling for a beloved, or a deeply hated kindred spirit?
Two thousand years ago, someone asked: "Teacher, how can I get rid of my confusion." Buddha smiled: "There are many ways, but do I really want to get rid of it?"
