If the valid cognition of the supreme knowledge that arises from meditation does not eliminate superimpositions, the meditative equipoise of [resting in] true reality — this meditative absorption of cessation — would not be unmistaken.” [In fact,] the valid cognition of the supreme knowledge that arises from meditation indeed eliminates the superimpositions that are discordant with this meditative absorption of cessation. However, when it eliminates [these superimpositions], in terms of positive determination, no direct appearance of mind and mental events not being established as anything whatsoever (such as them being unarisen) is brought about within such a cognition. The reason is that, once the valid cognition of the supreme knowledge that arises from meditation has eliminated all referential extremes of mind and mental events, it is absorbed in what is determined — the way in which mind and mental events are unarisen — in such a way that it is not absorbed in existence, nonexistence, entity, nonentity, appearance, or nonappearance at all. When resting in this meditative equipoise of true reality in such a way of not resting in meditative equipoise, there is no objective appearance and no subjective cognition that exist as one or different.
