Quite interesting - Mayan day/nights and earth periods

It seems Ra's use of the word manner that you have referenced now, refers to the polarity they choose. Thus, the manner of their leaving in the metaphysical sense in general (i.e. "..their manner of entry into fourth density") is to either move into the positive or negative polarity.

there is no polarity to choose for an entity who qualified for harvestable. the entity can only be harvestable ONLY if it has already chosen a polarity. an entity who has chosen positive or negative path and harvested, has no 'polarity' to choose when entering 4th density. entity qualified as positive, is positive, entity qualified as negative, is negative.

dont start making up things by ignoring plain english sentences in order to alleviate inconvenient information again.
