What does it mean to cut off the world and drink a cup of sorrow?

Cut off the world, let go of the lifelong fetters, drink a full cup of sorrow, and eliminate the lifelong sorrow. Pick a lovesickness, blow a song of sorrow and joy, dance a song of gone with the wind, and the song will end. Only by abandoning this golden melody can we break the fate of the world of mortals and break the heart of this life. Born in the world of mortals, grew up in the world of mortals and lived a life of fireworks. I don't think I can be completely heartless and quiet. However, if we can cultivate a blx in the secular world, it will be as calm and peaceful as a lotus flower, just like: Bodhi has no trees, and a mirror cannot stand. There is nothing in it, so there is no dust. This is an epiphany.
