For me it's various things, some of which are (in no particular order):
Quietude in myself, quiet in my surroundings
Being alone or being with people I care about (preferably one at a time)
Being with animals and insects, especially studying how they spend their days
Being at home, in my bedroom, reading a novel
Being in nature away from the noise made by people
Watching a bird flying high in the sky, especially a raptor
Looking at the moon
Being creative
I actually read maths books in bed.
I find reading this,
much easier than socialising with people.
I'm on page 712 of Calculus a complete course.
I was obsessed with an Atlas I got, in 1988, as a boy.
