A practitioner asks: “After the LHP intention pool is repurposed does it drain away and need topping up?” What can Creator tell us?

That is not the case. Your intentions are a product of consciousness and, as such, a creation of energy in a unique form that persists. Where it is and how it behaves and whether it can continue to affect other things is a function of consciousness as well, so the part of your intention launching the Lightworker Healing Protocol, or a prayer, or the DSMR Protocol, consists of energy and also information. It is actionable, according to the intent, for the divine to take the ball and move forward. Once that is done, further intentions, as parts of the protocol, and this can be included in prayers as well, instruct the divine to repeat the process again and again. That as well implies the answer to your question that, once created, that body of intention does not dissipate or weaken, it remains in existence and it can be acted on and repurposed again and again according to the wishes of the originator if such is stated as a part of the intention to begin with. It cannot be borrowed and repurposed by others except as instructed through the intentions of the originator. This is why your ordinary thoughts and desires cannot be borrowed and used without your permission, but their energy still exists nonetheless. It is the innovation of your channel to recognize that the persistence of consciousness, as an energy, can have further utility through being repurposed, but most conscious creations of human beings, and other sentient beings, has only a short-term influence and therefore subsequently remains idle—that does not have to happen.
