Sonia's work has been integrated into The Sofia Foundation (Stichting Sofia). This foundation was established when Sonia realized that her work would be part of a great plan that gives mankind its universal basic mysticism for the Aquarian Age. She understood 'her' work to be simply 'His' work and that is why The Sofia Foundation has not been set up for personal, but for broader, universal reasons. As such, The Sofia Foundation may also be a support for other mystics and workers receiving and/or applying the Aquarian mysticism in everyday life.
