from what I found asmi mana is strongly connected to sanna – it does not exists without perception and it’s created on the basis of perception and whole PS cycle related to vinnana also. I realized that my sanna starts to disappear and by sanna I mean here polluted perception with avijja so I guess it would be in relation to viannana. Generally for example once seeing something would trigger me I was surprised there was no trigger in my mind – normally would be there, my mind so to speak was ready to “grasp” that bhava of reaction but there was nothing to grasp which kind of shocked my mind. Path is very organic ,gradual and step by step unless you are high born beyond Neyya stage for most people it will be in parts. :)
