Cosmological model describing the Universe without the singularity and without the Beginning, that is, the eternal Universe evolving from the infinite past, is proposed. The main component of the model is the nonlinear Dirac spinor field with the power-type nonlinearity \( {\left(\overline{\uppsi}\uppsi \right)}^n. \) This field determines the evolution of the Universe so that the Universe always exists.
