...the deva spoke this verse...:

Who has not tamed all vain conceits,[1] Who lacks in wisdom, uncontrolled, Heedless, in the woods may dwell alone, Yet will not escape the realm of death.

[The Blessed One replied:]

Who, concentrated, leaves conceits behind, His heart and mind[2] set fair, and wholly freed, Heedful dwelling in the woods alone, Shall indeed escape the realm of death.[3]

Notes

1.: Maanakaama: "conceit and lust."
2.: Citta: "mind," but often like the metaphorical use of "heart" in English.
3.: He will pass "beyond death" to Nibbaana.
