О "духовных переживаниях" и Ниббане

Vasubandhu has to say:
The Unconditioned has no cause or fruit (effect) but it is both cause' and fruit.' It has no fruit because it is outside the three periods of time. No cause can produce it, and as inactive it can produce no effect.
The Unconditioned cannot have a cause because 'stopping' which is eternal cannot arise at any time after not having been before.' It may be objected that Nirvana cannot be eternal because a wise gnosis (prarisamkhyā) is its necessary antecedent without which it is not.
This gnosis culminates in the 'cognition of non-production' (cf. p. 167). This 'non-production has always existed by itself.
