The root of all that exists, samsara and nirvana, is one's own mind.
Primordially, mind is emptiness.
Merge into the sky-like absolute expanse, empty, luminous, beyond clinging.
Outside, inside; eyes open or closed, day, night; asleep or awake:
no difference.
During practice, after practice, mind, appearances: blend them.
Continuously, without wavering, merge completely with this vibrant, sky-like state.
