This is in the alternative health section so I will venture a reply....(first I thought this was about eyes
ojos or perhaps bears)....
to my singular selective opinion drawing solely from my own personal experience and considering myself as a healthy person....
Engageing this thing of orgasm as means is necessary(by my experience). In the end howeverI I think after many years with quiet mind at the point, the point becomes no orgasm. Instead reality itself by transference of concept to real all becomes the orgasm.
That is my personal feeling and to my opinion why I presently feel so healthy.
In orgasm one may find for that split second sicknesses disabilities of many natures other than of significant karmic import they dissolve for that split second....so generally I think on that basis is the principal of that thing.
Normally restriction of orgasm as a physical thing...it is considered most unhealthy. Medical people have stated this it is detrimental to the nerves.
Considered this only as a means of health...I practice no tantra of this sort, nor would I discuss such a thing.
So I guess it depends. Restriction, but really it is not a restricted thing as no conscious mind to this thing it may not happen,(it is not that it is stopped) Brought to peak then nothing it happens not but appears transferred it cannot be stopped perhaps it is so powerful that thing. It becomes then a source of health in a way. Not overtly karmically reducing as in one with no legs suddenly has them but of a covert sort...pain cold sickness of sorts will not happen as much.
Personally on health as I don't know many of what you are talking about alternative health...I have offered that.
But then done....in a healthy manner,it would not be engaged again...what the point of that?
