If an average person would need 29 years to clear their negative karma by working with an effective human healer all day, every day, for that length of time, how long does the divine realm need if a Lightworker Healing Protocol session is requested for them to be implemented as frequently as can be done, in perpetuity, in a way highest and best for their well-being?

This will need a corresponding length of time, and perhaps more, and the reason is that your question was asked and answered in isolation. That is to say, “What would a person need for complete clearing and healing if they were taken in isolation?” The fact that their karma is intertwined with so many other individuals creates speed bumps, so to speak, that slow the overall process down and its rate of completion. So this is why we now speak of two generations, which is somewhat longer than your interval, and we would count that as forty years of your calendar time. So this is not so very different a number, but allows some leeway for inefficiencies and the unpredictable nature of things, given human consciousness will continue to interplay with all that exists and will be a wildcard in terms of helping or hindering in individual cases, and perhaps both over the course of time for a given individual. And so the absolute time required for things to work out to benefit each and every human being to the degree desired is, in fact, unpredictable and only can be estimated. For those who have a shorter remaining lifespan, they will either be within the light and ascend from there or will reincarnate to be present in the physical for the grand event. Where they are will not matter, other than the fact they will still be needed as healers for the remaining time humans are in 3D. So this again presupposes there will be a body of lightworkers keeping up the requests from human side as needed to accelerate things. It will not matter if those creating requests for sessions in perpetuity have passed on. Their energy of intention, once created, remains in existence, and so the work it supports will go on exactly as intended through future incarnations of those targeted. It is only that with more and more healers, things speed up, so it is to the benefit to humanity and the overall enterprise if those healers already in their later years who pass on within this projected period, choose to return and reach an age when they can be contributing to healing of their brethren. So time will tell how things go, but the situation will only get better because many in the light are eager to join the party and especially now that the tool is in use and they will not have to reinvent the wheel, so to speak, but only need to be in a position to learn about the work, and have it resonate, and be guided to seek it out and embrace its use, and help the cause directly as you are doing and your practitioners.
