For some time, meditation has become a common activity in the West, whereas it was for a long time an Eastern prerogative. Nevertheless, many people devote themselves to it primarily, and even solely, for the purposes of relaxation and evacuating stress from their daily lives. And yet it is a fundamentally spiritual practice. In this opusculum, Serge Toussaint, the Grand Master of the French-speaking jurisdiction of the Ancient and Mystical Order of the Rosy Cross, explains how meditation indeed constitutes a source of well-being, but is also and above all a faculty that allows us to commune with our Inner Master, that is to say our soul, at its most divine.
