thanks, i think the sauna with beutifull peoples of opposite sex, can cause different sensations in your mind, body, imaginations and illusions... So i think it is good, you can follow them... For me it is too high...
But all practices can be used for different levels of your body or energy system... Opening heart is for example very high: connection of "heart" with sexual organs and so... Some peoples develope only definite "parts" in life, so if you haven't met in your life peoples with developed other "parts" or "levels" than you are happy... It is only my thoughts in this direction, may be not truth! Sure you can try to feed your body and organs with this heat, or stimulate point hui in sitting on the hot surface or lungs breathing the hot air! I haven't tried it may be... In any case energy exchange occurs on definite levels without physical touching... I have read that peoples in sauna have no masks?
looking for something, that i don't know ald looking for my errors in past. thanks for corrections!
