Why do you assume that there is a link to jhana via some unknown but assumed 'sexual energy' or that jhana arises by it being suppressed?
Why do you assume that there is such a thing as sexual energy? (dont tell me it is 'common knowledge'
All these are ultimately assumptions- jhana arises by suppressing FIVE hindrances- not ONE. So if we are focused on finding links with sex- that is exactly the one we will be focusing on.
There is no need to jump to conclusions about unconscious process which may or may not be. It is easy to suppose that something exists- but a bit more difficult to stay with the idea that one simply doesnt know and there are many possibilities.
