What is 'spirit', is spirit..what is flesh or material is material. Of the two, the spiritual experience is FAR more...umm..'awakening' than a physical orgasm...and actually lights up more areas of the brain, than a physical orgasm...the frontal lobe of the brain lights up, and more neurons are activated, than those who don't have that experience.
Now the brain can access different sensations of awareness, that unless you have experienced that, is really hard to explain...but one thing for sure, is that during a spiritual experience both 'time' and 'matter' take on a completely different sense of properties...and the experience is said to give the 'participant' a different view of what is considered to be the 'known reality'...so much, that often their 'reality' cannot be explained within the parameters of what we know, from this dimension....but rather this dimension has similar 'manifestations' that are indicative of ,as Crosby Still and Nash, described as, "...what is going on, down under you".
A lot of people, clergy especially, interpret 'spirituality' as 'another place in another time'...it's not. If it excluded 'now' it would not be 'eternal' or infinite...but to those who only count the physical experience as the 'ultimate', are limiting what they actually have access to. I cannot 'give' you that experience by explaining anything..nor can people give it to themselves, no matter how much they study the dogmas of 'religion', or adhere to the tenets of a particular sect of religion....or obey the 'rules' set forth by any 'religious' order....but your awareness, of things much larger and fuller, not subject to time fuses into your consciousness...and it's impossible, as far as I know, to discount it....as time goes on, there are reminders all along the way...that just keeps proving itself. Things fall into order...not an order that you can figure out, nor can you configure them out....but they make sense, as they unfold. That's one reason, people outside the experience can clamor all they want about a subject, that SEEMS to make sense to them...but it is only temporary, and in a short time is obsolete.
All I can say, respectfully, is it is like stepping into another dimension where your brain(for lack of a better analogy), sends and receives input far different than we do normally...and during one of these experiences, you have NO control, as to what is coming to you...hence the analogy of an orgasm is perfect!
Another thing to remember, is the experience is not just physical, nor mental...and is FAR greater than an orgasm. It is both 'great and terrible'!...and if there wasn't anything else attached to it, you wouldn't want one....only problem is, there is.
If you want to talk about it more, all I can do, respectfully is share what I know...but on this subject, I have no doubt.
When I went through mine, more than 40 years ago, and some subsequent to that, the things I saw and experienced, I have watched unfold as time went by up to the present, and as far as I can tell, beyond. It caused me to search out different writings to find consistencies,and lo and behold, they are there.
Without going into a lot of details, I will say that in music, for those who can compose, there is a wealth of info to process into sound!!
Originally, I was steered to the Mudcat Forum, by a world renown musician who, in her experience, shared a similar experience, and a common denominator that blew our minds...considering that we came from different cultures, almost half way around the planet.
Of course, I know I've been seen as somewhat of an oddball...but then, you should see it from my point of viewing!!
Anyway, I've answered you honestly and respectfully (this time..*grinning*..) and hope you receive it in the spirit that is intended.
