Meditation and 'not trying to change anything'
'Not trying to change anything' is a modern idea and is not what is taught in the original Buddhist teachings.
In the original teachings, there are four right efforts, namely: (i) effort to prevent unwholesome states of mind; (ii) effort to dispel unwholesome states of mind; (iii) effort to cultivate wholesome states of mind; and (iv) effort to maintain &amp; increase wholesome states of mind.
'Refreshing' calmness/tranquility ('samatha') is considered a wholesome state of mind that is preferably developed. To cultivate calmness requires a keen/observant yet very gentle effort to keep the mind clear &amp; equanimous.

For him, having thus developed the noble eightfold path...the
four right efforts... go to the culmination of their development.
[And] for him these two qualities occur in tandem: tranquillity
(samatha) &amp; insight (vipassana).
