“Bhikkhus, there are these three taints. What three? The taint of sensual desire, the taint of being, and the taint of ignorance. These are the three.”
A disciple of the Buddha,
Concentrated, clearly comprehending
And mindful, knows the taints
And the origin of taints,
Where they cease and the path
That leads to their full destruction.
With the destruction of the taints a bhikkhu,
Without longing, has attained Nibbāna.
