With the permission of our friend @reddust, I have had that experience, that of fasting and meditating. It is a rewarding experience if done out of conviction and with an objective in mind. I spent a lot of time in forced fasting (that is a long story that I will soon detail), and after that imposition, I found in meditation to overcome that forced fasting and for about ten years, the fast imposed by the authorities became my ally along with meditation, so I could overcome that time of torment... Our friend @reddust, you know what I mean.
