The Advayavada Foundation was founded in the Netherlands by Anne and John Willemsens. The stated purpose of the Advayavada Foundation is "to become a true part of the whole."

Notes:

the proclamation by all possible means of the conviction, embodied in Advayavada Buddhism, that man experiences as progress that which agrees with the direction in which overall existence moves forward over time, and that, consequently, the Noble Eightfold Path must be understood as a reflection at the human level, and in human terms, of that progress of existence.
