Trul Khor

Tsa lung Trul khor (lit. "magical movement instrument, channels and inner breath currents") known for brevity as Trul khor (lit. "magical instrument" or "magic circle;" Sanskrit: adhisāra) is a Himalayan tantric discipline which includes breathwork (or pranayama), meditative contemplation (or dhyana) and precise dynamic movements (or Body work) to centre the practitioner and to engender the body-mind precision of a keened instrument. "Lung" or "Tsa lung" is the Tibetan term for Qi and Prana (spiritual energy).

Chögyal Namkhai Norbu Rinpoche, a prominent exponent of Trul khor, prefers to use the Sanskrit equivalent term, Yantra Yoga, when writing in English. Trul khor hones the practitioner's faculty and supports the mindstream re-emergence of natural body-mind or primordial awareness or rigpa (cf. Dzogchen).

Trul khor traditionally consists of 108 movements, including bodily movements (or dynamic asana), incantations (or mantra), breathwork, and visualizations, all timed to heart rhythms. The flow or vinyasa (Sanskrit) of movements are enlikened to beads on a mala. The body postures (or asanas) of ancient Himalayan yogis are depicted on the walls of the Dalai Lama's summer temple of Lukhang.

Himalayan physical yogas vary between lineages and the complexity of the practices are not disclosed until a deep level of samaya is realised by the practitioner.
