Some are calling it “unconscious” as well, since it are actions by which there is no reasoning used but are more ‘spontaneous’ popping up out of the storehouse.
In research by psychologists, investigation tests are done, showing the (re)actions by this subconscious before reflecting is used. And the results are different. It cannot be other than it lays in the stored habits/ideas/karmic perception, which pop up when a connection with a certain object is made or to what the mind is pulled towards.
The actions’ source is not seen as we are not aware of this eighth consciousness/storehouse. And so by unawareness our circle of habitual tendencies keeps rolling. Looking within is what Buddha did, to see the cause of our suffering and not to look to the triggering object like a dog will run behind a thrown stick more than ones but a lion will not do that. We suffer again and again, run behind the stick, or behind the triggering object, we do not look within; to see the source where are suffering or irritations are coming from, we each time react on the object. A Lion would not run behind a thrown stick twice, but should direct him towards us who is throwing the stick. In same way when we turn our gaze within, be aware before reaction can pop up, we are aware and look within. By training so, karmic actions can be avoid and we make a chance the circle of suffering can be broken.
I believe Mara comes from the subconscious, but many would not agree with me. Mara is subconscious vibrations who come from others that starts subconscious processes within oneself.
