Yantra Yoga, the Buddhist parallel to the Hathayoga of the Hindu tradition, is a system of practice entailing bodily movements, breathing exercises and visualizations. Originally transmitted by the mahasiddhas of India and Oddiyana, its practice is nowadays found in all schools of Tibetan Buddhism in relation to the Anuttaratantras, more generally known under the Tibetan term Trul Khor, whose Sanskrit equivalent is yantra.
The Union of the Sun and Moon Yantra Trul Khor (’Phrul ‘khor nyi zla kha sbyor), orally transmitted in Tibet in the 8th century by the great master Padmasambhava to the Tibetan translator and Dzogchen master Vairochana, can be considered the most ancient of all the systems of Yantra and its peculiarity is that it contains also numerous positions which are also found in the classic Yoga tradition.
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 body postures (or asanas) of ancient Himalayan yogis are depicted on the walls of the Dalai Lama’s summer temple of Lukhang. Trul khor is the fruitful distillation of the confluence of centuries of ancient Bön movements, Indian yogic traditions, and Chinese movement forms (that developed into disciplines such as Tai Chi Chuan and Taoist disciplines).
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.
