This work introduces Harmonic Mirror Cosmology, a unifying ontological and mathematical framework that reconceives reality as a multidimensional field of scalar-phase coherence within consciousness. Drawing on the harmonic reinterpretation of mathematical constants by Sir Robert Edward Grant, the scale–phase conjugacy of Sir Arthur Eddington, and the operational language of Geometric Algebra, this model proposes that physical reality arises as structured self-reflection within universal mind. By redefining the imaginary unit as a real scalar contraction, reinterpreting phase as a fifth-dimensional mode of recursive awareness, and modeling coherence through multivector syntax, this cosmology bridges physics, metaphysics, and healing. The result is a breathing Kosmos — a living mirror in which science, spirituality, and society can once again cohere.
