My student wants to know, is requesting a Soul Reset for extraterrestrials by itself a useful undertaking? How many can be included by her in a single request for this to be done successfully?

So it is a fine idea to take this on as a project in its own right. To do the full Protocol is preferable. In her case, we would say it is best to limit this to 30. The reason for this is because of the huge nature of the Soul Reset. It requires a large amount of human intention and focus to reach the depths required. There would be gains, it is just that we would favor doing more complete work than would be the case in reaching out to a larger group. To do a group of 1000 would be meaningful. To do smaller increments and do them more thoroughly to us would be preferable.
