After living with these monks, as a monk, for many months in a remote village in Thailand, I realized that meditation is about developing the skill and ability to let go. As we sit in meditation, we watch our thoughts come and we let them go. Over and over.
We let go of the past and the future and stay rooted in the present. We let go of our ego and the carefully constructed sense of self that we have. We let everything go and we just sit in a deep peace and bliss, the only thing left after letting go of everything else.
