It's time to define some of the terms that I used in the past couple of videos. So, mind is part of the subtle body. Brain is part of the physical body. Even though in the past video I used it interchangeably, it's a wrong thing. Brain is part of the physical body. The smallest interval of time the brain can actively register is a tenth of a second. But we can develop electronics to measure faster and faster events. Like, we can measure microseconds, nanoseconds, femtoseconds—all of this stuff. But it's still seconds. Using electronics, we can go to really tiny fraction of seconds.

Now, the mind also can perceive small instances of time, except it depends on how much impressions the mind is carrying. And the impressions on the field of the mind are vruttis. In the physical body, vruttis means tendencies. In the mind body, vruttis are impressions left on the field of chitta. Unfortunately it adds a new word, chitta, which I will explain separately. But an ultra-clean mind with almost no vruttis can perceive a tiny, tiny, tiny increment of time called kshan.
