Man is a universe contained within himself, which he discovers when he seeks to understand reality through a refinement of pure thought in the light of the wisdom of love, as a light-dark reality, in the very image of the duality of the living world. The universe is always contained within us by its geometric forms and numerical figures in the spirit of Algebra which represents the mathematical thinking of man in the measurement of distance and direction, the speed of light, the fixing and positioning of the energies or particles of the space-time continuum in the first fundamental relationship of the survey L=l+d, adjoining ancestrality and cosmology The truth is always found in Algebra and Geometry is the support of the true truth of Algebra for man; then a fusion is necessary in everything to reach the true truth in a dual system with the two cones of light and darkness in the concept of symmetries.
