This is an issue that's been on my mind concerning spilling the semen, but more importantly what happens afterwards. There have been instances when, as a novice student, I failed to see the crucial urgency of not ever spilling, thus I would foolishly indulge in such; what's worse is that I thought I knew better, so I regard the karma I gained to be multiplied. I would wonder, though, about meditation and transmutation AFTER doing such a thing; namely, is there a certain period of time, so to say, that a devotee must wait before beginning to transmute and/or meditate (be it in alchemy or by means of pranayama, as we must consider the possibility of spilling during an attempt at alchemy)? My hypothesis being that since the semen has been spilled, it would most likely take some time for the body to regenerate such a potent form of energy, especially if a student had tried to be chaste for some time before such an occurrence. I also have in mind that in the Bible, in the book of Leviticus (I'm sure this is a popular book for the gnostics) it mentions that a man shall be filthy after such a discharge until evening. I have a vague idea of the symbolism behind it, but, me being asleep, don't fully understand what it could mean in its totality, and if it's even relevant to my issue. Thank you.
