Philip W. Groves taught students for over 40 years, in the fields of wholistic medicine and those searching for greater truth and meaning - before his death in 1999. The underlying theme of this work is guiding people to realise the abundance of their life, leading to the unfoldment of potential in life skills, creative expression and greater knowledge and understanding of the world we live in. These higher goals are explored by the use of practical application and real methodology which require time and effort or 'work' to find the beginnings of fruition. Esoteric Christianity is the basis and fundamental doctrine of this Teaching although the works of Emanuel Swedenborg and Gurdjieff are frequently drawn upon.

Philip W. Groves taught at Nature Care College as their senior lecturer for many years. He has a Ph.D in Biochemistry, a doctorate in Bio-Psychology and a Diploma of Naturopathy; he had practised as a psycho-therapist for many years, while also working in Industry as a microbiologist and chemist. In addition to this his fields of specialised interest and deep understanding extend to Egyptology, Comparative Religion (in particular Buddhism and Sufism), Botany and Biology.
