Always bear all impurities, the ascetic abandons all bonds; having exhausted all impurities, attachment has become immortality.

Samaṇo — ascetic, one who works on themselves. In ancient India, the śramaṇa is one who renounces the conventional world to seek truth.

Pecchatā amataṁ ahu — what was expected became immortality. Expectation transmutes: one no longer expects something from the world, but discovers what never died.
