Zen

According to Wikipedia

The core of Zen practice is seated meditation, widely known by its Japanese name zazen, and recalls both the posture in which the Buddha is said to have achieved enlightenment under the Bodhi tree at Bodh Gaya, and the elements of mindfulness and concentration which are part of the Eightfold Path as taught by the Buddha. All of the Buddha's fundamental teachings—among them the Eightfold Path, the Four Noble Truths, the idea of dependent origination, the five precepts, the five aggregates, and the three marks of existence also make up important elements of the perspective that Zen takes for its practice. While Buddhists generally revere certain places as a Bodhimandala (circle or place of enlightenment) in Zen wherever one sits in true meditation is said to be a Bodhimandala.
