Friend apophenia,
Though am nowhere near to such experiences that many of you have had but can understand what happens when the mind is free from thoughts. The gap/space created in the mind freeing it from thoughts is of observation.
In samadhi have heard that the heartbeat can be slowed at will which means the ability to keep observing any action in slow motion as the observer has elongated the time.
The greater the elongation of time the deeper is the past events [regression] become clearer too. Basically its a matter of wishing and that wishing again is a matter of choice which is mostly natural is presumed.
This is subject to confirmation by experienced individuals.
Love & rgds
Wonderful stuff, as always, ZenZero. I know, for a fact, that even at my "novice" stage of meditation, (38 years and counting), I can:
1. Lower my heart rate
2. Lower my breathing to almost stopping
3. Lower my blood pressure.
Heck, this is so well established now, I can do it consciously, just by tuning out thought and going to what many athletes call "the zone". On a common blood pressure/heart rate device, I have measured a drop of 3 - 5 points... while being quite awake and alert and that is without going into a formal meditation where breathing would also become shallow.
It's like when I had my case of kidney stones, before the pain became unbearable, I meditated and attempted to lessen the pain by reducing these three areas. It DID help ... for a bit ... until it was painfully obvious something was VERY wrong. That is when I began doing my imitation of a cow mournfully moo-ing on all fours. But, at first, during the onset, it DID help.
Likewise, when I am feeding my wild deer, I put myself in "the zone". It
does seem to calm them and they come over to investigate.
What I am thinking is this present conversation is not at all unrelated to the OP. I think it has everything to do with the OP, quite frankly. The point is, if one wishes to do these "unusual" activities, it takes a tremendous amount of time and patience to learn. Athletes spend some time, endlessly repeating tasks to put themselves in "the zone", so their body reacts automatically. My guess is that it is similar with the so-called siddhi's.
In my view, one could indeed spontaneously burst through normal abilities and enter into extraordinary abilities, but one must expect a long hard road before reaching the prize. In theory, by the time one gets to that prize, they will no longer care much about said prize. Again, in my view, it is, like bliss, simply part of the fringe benefits package of expanding awareness.
