Tony Parsons gives talks and facilitates investigation and discussion on the nature of Advaita Vedanta and non-dualism.He works both in the UK and internationally and his books are published in many countries.The fundamental principle of his work is to define the non-dual and impersonal nature of reality and to expose the dichotomy of the dualistic belief in a progressive path leading to spiritual attainment. The origins of this non-dual communication can apparently be found many centuries ago in the teachings of Lao Tzu, Saivite Tantra, Advaita Vedanta through the teachings of Shankara, Gaudapada and others, Dzogchen Buddhism through the teachings of Longchempa, Mahamudra and others, together with the original precepts of Zen Buddhism with the teacher Huang Po.The expression of the non-dual perception can also be found in Christian mysticism. However, Tony Parsons also includes in his communications recent scientific discoveries that have been made by neuroscientists and biologists which further reinforce and support the non-dual perception. There is also an emphasis in his work on the way in which physicists are now reaching the same conclusions about our reality as religious mystics have been expressing over many centuries. So, although this message has its origins in seemingly recognised traditional teachings, it also embraces recent scientific discoveries which further confirms its authenticity as an enlightening and comprehensive communication.
