It may be that techniques have a certain life span in this spiritual business. If you get one too early, it won't work. If you use one for a long time, it might come to a natural interruption; you stop, then start again later. It might come to a natural end. For example, with TM, you sometimes switch techniques, advancing the technique. Other systems may do the same, they give you techniques for a certain specific purpose, and if that purpose if fulfilled, you need it no more. For example, Zen koans are techniques for illuminating certain facets of experience.
Starting and Stopping are natural transitions. For example, if you get hit by a car traveling at 200km/hr your spiritual progress transitions to an absolute value.
