A follower of René Guénon, Valsan considered Hinduism, Taoism and Islam as “the three main forms of the present traditional world, representing the Middle-East, the Far-East, and the Near-East, as reflections of the three aspects of the Lord of the World.”
The Islamic doctrine is formal on the point that all the Divine Messengers have brought essentially the same message and that all the traditions are in essence one...As regards the Islamic form of the tradition this is in any case originally and essentially based on the doctrine of Supreme Identity...
Valsan introduced the study of Islamic esoteric doctrine, in particular that of Ibn Arabi and his school, into the context of the "traditional studies" based around the work of René Guénon (Shaykh 'Abd al-Wahid Yahya), of which he was a constant and effective defender. Although initially a disciple of Frithjof Schuon, he later distanced himself from Schuon and the Traditionalist School, declaring his independence in 1950.
Valsan served as the director and editor of, and regular contributor to, the journal Etudes Traditionnelles from 1948 until his death in 1974. Valsan died in Paris, France at the age of 63. A collection of his articles was republished in a posthumous compendium entitled L'Islam et la Fonction de René Guénon (Editions de l'Oeuvre, Paris).
