The view of Tendrel (Tibetan), that 'everything that arises is mutually interconnected', can be considered Buddhist Philosophy's quintessential contribution to the world. This view originated in 5th Century BC in India by Buddha Sakyamuni and was investigated and debated by the Buddhist scholars at the Nalanda University, North India, right up until its destruction in the 12th Century AD. In the 8th Century AD the Tendrel-view together with other facets of Buddhism was introduced in Tibet, which became the academic basis of an extraordinary scientific and method-orientated tradition. The expositions of Tendrel survived and had thrived in Tibet up until the middle of the last century, when the Chinese communists took over the government of Tibet. The events that followed, forced Buddhist Scholars of Tibet to flee to India and elsewhere.
Thereby passing on this otherwise hidden knowledge to the world at large.
The view of the interrelated nature of existence, Tendrel, has slowly but surely developed within modern science along with the development of increasingly more sophisticated research tools for revealing the truth of reality. And also the theorem of Tendrel, as taught within the Ancient Eastern Tradition, has gradually caught the interest of Western scholars and inspired many people in the modern world.
Tarab Tulku Rinpoche, one of the most renowned Tibetan scholars of our time, lived in the West for over 35 years and it was here he came to formulate his deep understanding of Tendrel in terms of the paradigm of the three pairs of interrelated opposites, joining in unity:
1. Subject (mind) – Object (reality)
2. Mind – Body
3. Potential Field – Matter
To render these interrelationships comprehensible and to facilitate their deep understanding – a valuable contribution to humanity – is the heart of Tarab Rinpoche's integral approach.
The universalities are extracted from the traditional Buddhist “Inner Science of Mind and Reality“, as taught in the Sutras and Tantras, based on Tarab Tulku Rinpoche's own exploration and further elaboration based on resulting insight. Tarab Rinpoche reached this paradigm through 30 years of work, already started in Tibet before 1959. He crowned it "Unity in Duality" (U.D.).
Unity in Duality is a modern translation of that which Tendrel refers to.
In cooperation with Lene Handberg he presented his work in five disciplines:
UD Science of Mind and Reality
UD Personal Development
UD Art of Relating
UD Psychotherapeutic Application
UD Spiritual Development
In this way the ancient knowledge, founded on the Tendrel-view, was established in the present day as an accessible and practice orientated system.
Unity in Duality is not bound by any culture or faith. It addresses the universalities and can therefore be used in combination with any culture, faith or by people of no faith.
Unity in Duality contributes greatly to solving mentally created problems, which are increasing rapidly due to the stressful conditions created by the highly technical and rational culture that is prevailing today in many parts of the world.
Unity in Duality is relevant for all walks of life: For lay people and personal as well as for professional application. It introduces effective methods for creating inner and outer harmony, mainly through practical application at present in the fields of human relations, communication, education and mental health. Likewise it has great importance in connection with research in different scientific fields.
