David T. Johnston is a practicing psychologist living in Victoria, BC, Canada. He resided in Pondicherry (now Puducherry), India from 1970 to 1973, where he was introduced to the Integral Yoga of Sri Aurobindo and the Mother. He lived there during Sri Aurobindo's centenary in 1972. He subsequently studied at the C.G. Jung Institute in Zurich, Switzerland in 1975, the year of Jung's centenary. On several occasions, for extensive periods of time, he has visited Auroville, a township near Puducherry dedicated to the Mother's vision. He received his Ph.D., phil. in Clinical Psychology at the Pacifica Graduate Institute in Carpinteria, California in 1996.
Dr. Johnston is also an artist, where his art is a meditative means for him to enhance a living relationship between consciousness and the unconscious.
In Jung's Global Vision: Western Psyche Eastern Mind, Dr. Johnston outlines the striking similarities as well as differences between the path of individuation as outlined and lived by C.G. Jung, and the Integral Yoga of Sri Aurobindo and the Mother.
