For this you will need to know how to enter a timeless/spaceless trance, and also a touch of precognition. Start by projecting into the target and enter such a trance. Intuitively feel out their being, noticing every part of it including wherever it will be in the future. Notice all the possibilities and 'timelines' that exist for this person and move them around a bit so that they correspond to what you wish to occur. Alter the person’s relationship to the rest of reality so they may express a particular trait, such as heightened psionic sensitivity, throughout their existence. There are many things that can be done due to the great freedom this particular technique allows.
