The article is devoted to Meister Eckhart’s interpretation of ontological structures of reality in which the concepts of being, nothingness, existence, and Godhead play an important role. The article discusses: 1. the interpretation of being and nothingness in the prologue to the Latin Opus Tripartitum; 2. the interpretation of existence and Godhead in German works; 3. the placement of these deliberations in the context of Eckhart’s conception of abgescheidenheit. The article’s main thesis is that in his ontological reflection, Meister Eckhart comes close to thinking about the essence of reality as Will, which is a clear anticipation of an important current in German philosophy.
