Maimomides (Rambam) writes that our world is below the axis of time and the spiritual world is above time. Therefore, as we move closer to spirituality, we suddenly begin to feel that one second is a very long time. We can fit many events into the period from the beginning of one second to its end.
In modern technology, devices work at high frequencies and are able to process millions of impulses per second, which they could not do before. The spiritual world is way above modern technology and works at an infinite frequency. Therefore, there are no short moments in spirituality, and every moment there is infinite.
