This says it all in about six or seven minutes. The power of decision and its window of opportunity.

We have a tiny fraction of a second to consciously recognize what arises from the subconscious and decide whether or not to act it out, and this is where meditation is a powerful tool. When clarity and discernment are cultivated to a sufficient level that window seems to expand. I don't know if it's a sort of time dilation but to me it seems like time does slow down and I am much more aware as the first tiny seed of a thought begins to bubble up out of the subconscious, thereby strengthening and empowering the power of decision.
