the unborn, is described by Buddha:
The born, become, produced, made, fabricated, impermanent, fabricated of aging & death, a nest of illnesses, perishing, come-into-being through nourishment and the guide [that is craving] — is unfit for delight. The escape from that is calm, permanent, a sphere beyond conjecture, unborn, unproduced, the sorrowless, stainless state, the cessation of stressful qualities, stilling-of-fabrications bliss.
Doesn't this describe nirvna? Can the description infer us to a true-self (atta), not-self (anatta), or anything else other than what is listed? Can you infer emptiness? As I was saying to other, losing with a self is so bad, I couldn't justify calling this so-called unborn a self, and it wouldn't be me or mine unfortunately. Regardless, this text says permanent, and what is the harm in selfing this permanence? What is the harm? What was permanent is no longer mine?
It doesn't say 'end of defilements', 'end of existence', but perhaps you can infer that. How do you infer it?
