I would like to think such a person can exist. For i strive every day to achieve just that. However to me that would take a perfect level of impeccability that once achieved their spirit would no longer need to exist on this realm.
Now. Say such a person did exist and engaged in sexual activities. I am not sure that would be possible. Because the point of orgasm alone would be influenced by the other. Otherwise there would be no need to participate in sexual activities.
Quoting: Qarley Most of them do leave when they get to that point. To achieve it, one must face death itself. But some choose to stay awhile longer, their death (out of respect) gives them that choice.
This sexual stuff is discussed in Castaneda's works. It was implied that 'a sorcerer's party' did involve a sexual relationship of some kind between its members.
Also, it was implied that the 'formless' ones often used the sexual bond with some of their apprentices to help them achieve 'formlessness'.
Now when you say that the point of orgasm would be influenced by the other...you are dead on. So, when two people (or more) with an impeccable spirit were engaging in sexual activity, the 'normal' amount of sexual influence or intent flowing around the room would be, in theory, vastly transcended.
The act alone might imprint the abilities of one member onto another. It's not something that could be done, in theory, all the time. It would be something that was done for a specific energetic purpose, toward an agreed upon objective. I'm sure that if such a thing occurred, there would be surprises. However, 'formless' people have achieved the ability to improvise and adapt to almost anything, so perhaps something interesting could, in theory, come out of it. Jeez, the puns. The puns.
