16.1.p15

“Great King, you should know that this is surely the case for ascetics and priests who investigate the happiness of respite, the happiness of being well gone, the happiness of the ascetic, and the happiness of nirvāṇa. They understand from their investigations that the firepit of lustful desire is like a chain of bones, a pile of flesh, a sword coated in honey, a branch broken by an abundance of fruit, a loan that’s due, a sword tree, a poisonous tree, or a poisonous herb. They all investigate and comprehend that this is the case. Having fully understood it, they know what produces the fire of desire, and then they surely can cross the flood of desire, the flood of existence, the flood of views, and the flood of ignorance. They will surely have crossed the flood of desire, the flood of existence, the flood of views, and the flood of ignorance.
