What is your preferred form of meditation?

With walking meditation I feel the greatest benefits.
It calms me down immediately and allows me to stop, or at least minimize greatly, my thoughts and emotions, and gives me a sense of balance.
This usually work best in nature or forests.

I also like sitting meditation while listening to certain meditative sounds, or even without any sounds, though I still find it difficult to not want to keep track of the time and how long I have been sitting for.
When i do sitting meditation, I usually do it with either a guided meditation, or a timer.
