10.1.p5

While practicing that carefulness, a monk secludes himself in a quiet place, and he’s constantly aware of himself and explores himself. He’s freed from thoughts contaminated by desire and freed from thoughts contaminated by existence and ignorance. Once he’s freed from them, he attains knowledge of that liberation: ‘Birth and death has been ended, the religious life has been established, and the task has been accomplished. I truly know that I won’t be subject to another existence.’”
