Anything that gets me out of my ego-being state and into the essence of being and awareness of the now, divorced from stories of the past and future. One of my guides gave me a lecture on that. Course in Miracles. People's brains are like that due to how we evolved, how our minds relate to our past and future. We don't concentrate on the now.  For the bulk of human evolution, people needed a brain and a mental state that could encompass the memories of trial error, cause effect, and they had to keep alert to audio/visual stimuli and messages from the environment for survival. We can look at now as nothing but a big distraction, but it serves a purpose.  It can bring us to Stillness where we hear the inner voice of God.
