Samskaras: Impressions from experience stored up in memory. They have energy, and influence character and personality. Although usually considered to be positive or negative, really they are neutral.
If we observe closely we will notice that the actual moment of recognition of inner change occurs in an instant. It is like the blink of an eye. One moment we are seeing something in the usual way, the next, in a blink, there has been a change, perception has shifted or altered. Of course because it happens so quickly we may miss it, but that’s another matter.
It’s like a bubble rising from the bottom of a deep lake. There may be some time between the moment of release at the bottom and the moment it arrives at the surface, but when it breaks through at the surface it happens in a moment. In the same way what has been 'bubbling under' in the mind for some time breaks through from the unconscious to the surface of the mind in an instant.
Even when something appears to dawn on us gradually, if we could slow down time we would find that this gradual recognition is a series of instant moments one after another that add up to what we later call recognition.
