There are three points that I find confusing concering this topic.
Buddha says that the twelve ayatanas (and therefore the five skhandas too) are the All, and that nothing beyong the All can be described or explained. Yet, he describes nibbana as supreme happiness. Is then nibbana within the All, but the parinibbana beyond?
Also, even though the intellect (manas) is the sixth ayatana, and therefore within the All, elsewhere the Tipitaka says that there is a type of consciousness (vinnana), "without features" (anidassanam) - that is beyong the All, but consciousness is action of the intellect, and those are then two contradictory statements. What is the explanation of this?
And finally, I want to ask for an explanation about some points of the awakened mind and the plane of unconscious beings. Firstly, I want to ask is the nibbana same as the stopping of sankhara? Secondly, is there any explanation of the asannasatta deva loka as to why are persons born in there? There they are born only with the body, only with the first skandha, meaning that to be born there, they previously had to be in a state where they have calmed the cittasankharas, where they have achieved the mentioned consciousness without features, and gone beyond the All, is that right? If so, why are they born there, instead of attaining parinibbana? Also, if it is true that by stopping cittasankharas one enters nibbana, being that asannasatta devas by definition don't have cittasankharas, that means that they are in nibbana, and that after death, they should attain parinibbana, and not be reborn, but Buddha says that after dying the asannasatta devas do not attain parinibbana, but are instead born in the lower planes- how is that explained?
