Often people refer to nibbāna with the cessation of all mental defilements. However, does nibbāna also encompass 'momentary cooling off', for example when one engages in the various contemplations / mindfulness of breathing? If I, for example read suttas, I feel my mind is getting calmer and calmer, as if a heavy burden wanes.
Another 'momentary nibbāna' would probably be samādhi, where all hindrances lie dormant, right?
