I used to be similarly plagued with this also, but I've found a way through that works for me. It might or might not for others, but: I take the suttas as the ultimate guide, and I listen to various teachers who I feel can explain, or elucidate and make clear to me what the suttas are really getting at - which is a long-term process, and not gotten straight away. Yes I live with some uncertainty, but I keep investigating to perceive what leads to more wakefulness, more clear seeing, less doubt. If 'your' way of calming the mind leads to seeing the impermanence, unsatisfactoriness and self-less-ness of the five clinging khandas, then it's working for you. imho. If your samadhi practice is leading you towards disenchantment with clingable phenomena, never mind that it differs in some details to what some others do!
Then the Blessed One, picking up a tiny bit of dust with the tip of his fingernail, said to the monk, "There isn't even this much form...feeling...
perception...fabrications...consciousness that is constant, lasting, eternal, not subject to change, that will stay just as it is as long as eternity."
