transitioning from other practices (re "sharp cutovers"):

If you are coming to these practices from many hours of other practices or another lineage, it can be sometimes helpful to deliberately and exploratorily interleave your old practices with new ones, prior to a bootstrap of greater and greater intuition for what to do when and how. (This might be on a timescale of seconds, minutes, hours, days, or weeks. It just depends.)

"Sharp cutovers," where a person leaves an old practice behind, for a new practice, and never touches the old one again, can lead to problems, in part because a person will have to touch the old practices (or their results), again, eventually, in order to make continued progress. And, it's sometimes easier to do that sooner rather than later. (See, in part, the idea of "redo-to-undo," later in the document, as well as the idea of "layering.")

It's like the old practice, depending on how much "undoing" you were already doing, has built up scaffolding, built up more each time one engages the practice. And, it takes some fraction of that time, in the future, to take down that scaffolding (while keeping the benefits). If one switches over to doing a new practice, too soon or too completely, it can leave scaffolding behind that eventually gums things up, later. (Though, you will have the opportunity to clean things up, then, at that later time, of course; it just might be at greater expense. Or(!), you'll have much more experience in the future, and it's much better to just wait to go back (and you may spontaneously find yourself there when it's time, in any case). It all just depends.)

Note also, anyway, that many people should just keep doing something in the space of what they've been prevously doing, for a time, or on and off. The "meta framework" of this document smoothly admits any and all practices (see the preliminary/auxilliary practices, main practice p2, etc.) Many people import practices from other lineages or find those practices already in the document, in some same, similar, or otherwise nearby form. (Eventually one moves beyond "practices" to just step-by-step, concrete, fine-grain doing, a la radically unstructured global wayfinding.)

So, if things feel fine, or going back and forth is confusing and "grindy" it's (maybe very) ok to just cautiously go ahead and trust your felt/intuitive sense of what to be doing (which could be new things or old things or creative mixes or amalgams of the two). This is, at least, just something to keep in mind. You'll eventually return, somehow, to the things you've already done, maybe liminally, at least once, and usually many times.

In any case, it can be helpful to keep in mind that some people are sometimes inclined towards "sharp cutover(s)" in a possibly problematic way.
