When doing Deep Subconscious Channeling with Trauma Resolution, are changes to events in other timelines felt instantly in the current moment, or will that depend on when the changes are implemented relative to the current timeline?

The latter is one determining factor. There are relative differences, with respect to time, of events taking place among parallel lifetimes, so that is one factor that will determine how quickly cause and effect will come to bear for something nearer or further from the current life where the symptoms are rumbling. A much larger variable is the amount of time it takes for the healing to be complete in a functional sense, in other words, preventing an event from happening that adds weight to inner discord in a past life connected to a current dilemma may undo some of the total negativity participating in the causation of symptoms experienced by the client currently, but will be only part of the problem, and what needs to happen is not only to take away from the negativity in that moment but for the subsequent benefit within that timeline to be allowed to happen, to play out a bit, so that a greater positivity will loop into the present lifetime and bestow a blessing for the client in their current life. So the reality of trauma is it not only introduces pain and suffering, but it takes away the positive benefits of an individual's ongoing life experience that would otherwise take place, and the Law of Karma must figure that into the equation with respect to restoring things to bring about the ultimate healing and rebalancing needed to finalize a rewriting of the energetic signature stored within the akashic records to reflect a state of neutrality. So, in a sense, removing the trauma is a first step and there needs to be a subsequent contribution of the timeline being healed—that will be somewhat time-dependent because there will need to be at least some looping to connect to the present moment from the changed circumstances, adding something positive to the universe that was taken away by the trauma prior to the healing. So this is another variable that is subject to many constraints and influences in the back and forth nature of how energy impinges and is utilized by the players who were influencers of the client receiving the healing work. As you are seeing, it is even more complex than you first envisioned, that simply preventing a dire event is all that would be needed and the effects of the trauma would simply disappear, and a person fully restored as though it never happened, with no diminution of the client's life remaining. In actuality, many times there is but a partial restoration following intensive healing work because what is still remaining is the reconstitution of the players on the other timelines receiving healing, and the need for the consequences of the healing, having been put into motion, becoming manifest and influencing the client in their current timeline. This crosstalk will continue because it is the nature of energies to do so. There is a vast interplay of one thing affecting another, one person affecting many others, and being affected by many others in turn, going on constantly, and it is that vast mechanism delivering a kind of composite sum total of positivity versus negativity. But this is in fact not just simply a single signal that could be considered to be either high or low, positive or negative, but comprises many signals affecting many levels of the being with many differing perspectives and karmic consequences underway influencing the individual and their being—from their physical health, stamina, and resilience to their mental capabilities, their emotional health, current mood state and its range of extremes, and many aspects of the personality—all will be modulated by this flow of energy. Things are always in a state of flux. Healing will simply change the nature of that flux to a somewhat differing but equally complex sum of many, many influencing timelines and events, adding and subtracting, modifying some things and not others within the being, and so on. So this complicated interplay will always make it difficult to tell who is doing what to whom, but the point is to make the investment in changing things for the better—that will have a karmic benefit of its own regardless of near-term outcomes.
