Although ultimately a Heraclitan answer, no-self points to the impermanence and transience of all that may be experienced; even the qualia of your sense experience can vary depending on your state of health, or as an effect of taking psycho-active substances; or, for that matter, the impermanence of conciousness itself, which can be turned on or off by accident, as in coma, or by the use of anaesthesia; or can be fractured into the unintelligible kaleidoscope and meaninglessness of dementia.
But it may also get you to dig deeper, to see the whole “you” package as no more than a temporary phase that is to be passed through, perhaps to be replaced by another “you” at some other time or place.

Now, having totally undressed yourself and discovered that you are not your cloths, get dressed again in your being, in your meanings, in your culture.
