Vipassana involves choosing where to attend, which is not a form of action. Feeling gratitude is choosing where to attend, which is also not a form of action.

Turbochargers in engines convert the force of the exhaust, using a turbine, into increased air intake pressure, which increases the power of the engine. This is analogous to taking the effect of the mind wandering (exhaust) and converting is by feeling gratitude (turbocharger) into increased attention (increased power).

Yes, engines do stuff, but it’s only intended as an analogy.
