Nothing to do
It's a hard feeling to describe.
Meditating, for me, is often about convincing myself there's nothing to do.
Letting things happen.
Which doesn't mean doing nothing. Quite the opposite.
But you let go of the part of you that worries about what to do.
You switch to spectator mode.
Everything important will get done. (By magic).
But in an order you don't know.
Some of what you'd planned will be left aside.
Other things you weren't expecting will be carried out with care.
You learn what really matters to you.
Far from goals and structured thinking.
For me, that's the real foundation.
The one we often don't dare let emerge, out of fear and a desire for control.
