Why are people saying nonsense like you don't loose it? You do project energy, including preheaven and wuji energy, called higher shens in early daoist writings because they ARE shens/mind aspects. The elixir is found not 'created', by becoming it.

So stuff is projected and that could be taken to be your "willpower" how much you can control to project. However, only postnatal energy is consumed, the higher shens are merely used, like RAM memory in your computer. Used for a while then released.

The amount of energy 'lost'/ejaculated away in simply speaking, or talking your mouth mindlessly, is NEGLIGIBLE. Do you feel drained after? Inside and in the quality of your actions - NO. You feel more drained from browsing pornography for 10-30seconds or getting aroused by a live chick on the street or beach.

So do not worry. Once your 3 dan tiens are developed, alive, pulsing like your organs and probably 'merged', you will probably want to be able to hold some of your Yi on the LDT nonstop. Your multitasking and imagination will be developed enough to be able to spare it effortlessly, Right now you cannot.
