A practitioner asks: “I want to know about the expression, ‘Let what comes, come. Let what goes, go. Find out what remains.’ Is this a kind of ancient quote that is supposed to help one come to peace with something a misguided concept?”

In effect, it becomes a misguided concept when it purports to give you a guide for living as the be-all and end-all in how to respond to the challenges of life and take action that might be helpful for improving things. This is a vague, most nonspecific of descriptions, mostly encouraging a passive response. As such, it is not helpful. If you wait for life to happen to you, it will be a much more limited life than would be the case if you are in active pursuit of new challenges, new learning, and growth that will result, that is planned through a passionate effort to seek out the novel and to fill in gaps in personal development, and so on. Similarly, anything that escapes you or goes into decline or is taken away is food for thought to consider what might have happened to bring that about, to learn from it, and perhaps head it off the next time, by doing some healing work and better preparation to hang on to what you gain, so it cannot be lost, and so forth. The one admonition that is positive is that of finding out what remains. But here again, it is the vaguest of instructions with no hint at how to go about this effectively, nor what to do with the information one learns, what lessons to draw from it. So overall, we would say this is simply sophistry of an older era that has outlived its place in the generation of modern humans who are better educated and more sophisticated and increasingly, with your assistance, more spiritually astute, given our teachings about the need for partnership with the divine in all one takes on. That is an active, not a passive, relationship and life process for proceeding with purpose and greater strength.
