You cannot understand something unless you experience it.
Rishi Vishwamitra, who was a king before becoming a brahmarsi, has meditated for thousands of years as described in Ramayana. The immediate question which would come to anyones mind is how can a human meditate for such a long time, and the question of food follows. The food thing is clear like surviving on fruits initially and then on air and then on nothing (not even the breath). Lets address the time part of it here.
Einstein's general theory of relativity which states how time is different based on space is accepted and proved experimentally. "When spending few minutes in a very strong gravitational field (planet close to black hole) is equivalent to years in a weak gravitational field (Earth in relative scale) the same can be extended to the deep state of meditation."
Let's come to the actual experience part. Meditation during a solar eclipse is considered powerful. You can get more information here (link). The last Solar eclipse which happened in June was a time wherein I desired to get more spiritual knowledge. Whenever I have meditated I was never able to go beyond 25 minutes. On the day of eclipse, I started with mantra chanting an hour before the core eclipse time and reserved meditation for the specific time window. I meditated during that time window and by the time it ended I felt like the usual 20-25 minutes have gone by, but the time elapsed was 45 minutes.
