Where did Thai Yoga Therapy come from?

The seventh (and last) law of yoga is The Law of Dharma. We all have a purpose in Life. We all have unique abilities and our own way of expressing them. There are needs in this world for which our specific talents are ideally suited, and when the world’s needs are matched with the creative expression of our talents, our purpose—our dharma—is realized.
            The practice of yoga provides a direct mechanism to release energy blockages in the body (thai therapy does this also on a bigger level). When obstacles to the flow of our vital energy are removed, we become capable of expressing more expanded aspects of our self. Increasing compassion, wisdom, and playfulness are evidence that your life is flowing in accordance with the Law of Dharma.
            The history of Traditional Thai Partner Yoga dates back about 2500 years ago, along with the introduction of Buddhism from India into Thailand. It became one of four branches of traditional medicine in Thailand. Herbs, Nutrition, Spiritual Practice and Nuad bo-Rarn (Thai Partner Yoga Therapy) which means "ancient body of work"
             Around the second century B.C.E, there was a movement of medicinal practices into Thailand that accompanied the migration of monks and Ayurvedic doctors from India to Thailand around this same time.
Nuad bo Rarn developed with in the walls of Buddhist monasteries and temples.
               Traditionally, when there was disharmony in a villager's life, whether it be physical, mental, emotional, spiritual, they would seek relief from suffering from a monk within the wallls of the temple. Prior to practicing Nuad bo Rarn, the monk would have undergone deep mind, body, spiritual study and transformation in order to practice this type of healing. It is impossible to separate TPYT from the spirituality of its beginnings. The most predominate aspect of TPYT is that it is first and foremost a "spiritual Practice". The Bodhi Yoga philosophy roots TPYT in Yoga and Ayurveda, rather than massage. Thus, when practiced from it's original perspective, it is first and foremost a form of Ayurvedic Partner Yoga.
