A client wants to know, can we make a successful request to do Spirit Rescues for all of a client’s ancestors, or short of that, their soul collective?

The requests can be made but the limitations you have outlined are very, very real. It will vary according to the practitioner in how many can be successfully rescued. So in the absence of knowing the figures, there can be other strategies applied. There can be groups done, one by one, and then testing to see if there are remaining spirits will indicate if the desired task at hand has been completed. Those capable of receiving definitive information can get an accurate number of such beings relayed to them. It may be a daunting figure. So this again is an illustration of the consequences of knowing one may create a quite large burden for oneself, with all its karmic implications, as well. It is one thing to be completely unaware of the existence of a problem. It is another to be aware and to do nothing. That awareness creates an inherent obligation, even when righting the wrong is extremely difficult and demanding. The obligation has been created, and this puts a person in a position of taking on a potentially quite large burden. This is an example of a self-inflicted karmic wound, but may be embraced willingly by the divine human wishing to help. This is what you do with each and every life in coming into the physical, you are embracing a problem you are ill-equipped to solve, and will unlikely do so as an individual. All of the damage you witness you become entangled with, and share in its burdens and responsibility for existence and persistence in physical reality, both. This is not a reason to disengage and ignore everything, but is simply a description of how things work, which you are probing. So it is something you can ponder, and take into account as you move forward and have ideas about various enterprises, their do-ability, and your suitability to spearhead them, or in what other way you may wish to participate, and the trade-off for you in accepting the burden and responsibility, in light of other obligations that cannot be surrendered or substituted.
