Empty yourself of everything.
Let the mind rest at peace.
- Lao Tsu
This is certainly easier said than done for me. My brain goes at 100 mph all the time. There is not much peace to be found in that.
But, in an effort to find some, I started meditating years ago. It is one way to get to a bit of peace, although I've never been able to empty myself of everything. It might, indeed, be nice to rest the mind briefly.
