Where two practices meet
4,304 pairings drawn from 65 practices, most-searched first.
Two methods you already know can sometimes do something together that neither does alone. Sometimes they pull against each other instead, and the page for that pair says so rather than pretending otherwise.
Every page here takes one pair and asks the same two questions: what principle do both of them rest on, and how does each one sharpen the other in practice. The comparison happens at the level of the principle underneath, not at the level of technique — two methods that look nothing alike often turn out to be working on the same material from different sides, and two that sound like the same idea often are not.
A pair appears once. The page for one practice and another is the same page read from either side, so the listings below name each pairing by the practice it starts from.

Possible Selves Exercise

A future-self picture with no lever, and a strength with no target. One reading of how pairing them changes both.

Vivid future-self imagery can motivate you or spiral into dread, depending on how you hold it. A mindfulness skill decides which one happens.
