Sometimes such practices are simply concerned with being mindful. In zazen or ‘just sitting’ practice from the Japanese Zen tradition, one sits calmly, aware of what is happening in one’s experience without judging, fantasising or trying to change things.
A similar practice in Tibetan tradition is dzogchen. In both cases, the meditator sits with their eyes open. (Usually people close their eyes to meditate).
Zazen and dzogchen practices gain depth from the underlying belief in the significance of being in the present moment.
