Objectives: The main purpose of this paper is to study the theory of Dhomothetic deformation of an η-Einstein Para-Sasakian manifold. Methods: A deformation technique is employed to solve the resulting problem. We provide its application in the general theory of relativity. Findings: Section 2 deals with recurrent and symmetric Para-Sasakian Manifolds. In section 3 we have defined and studied projectively symmetric Para-Sasakianmanifold. The notion of φ -holomorphic sectional curvature in an η-Einstein Para-Sasakian manifold has been delineated in the section 4. In this very section, we shall study the relevant commutation formulae which give rise to the required curvature tensor. The obtained results were compared with the previous works (1--3) in this field andwere found to be in good agreement.Novelty/Conclusion: The study concludes the following results: 1. If n-dimensional Para-Sasakian manifold is to be recurrent projective symmetric then the recurrent projective curvature tensor vanishes identically. 2. If n-dimensional Para-Sasakian manifold is to be projective semi-symmetric then the semi-recurrent projective curvature tensor vanishes identically. 3. If n-dimensional Para-Sasakian manifold is to be projective scalar-symmetric then the scalar projective curvature vanishes identically. 4. If D-homothetic deformation of η-Einstein Para-Sasakian manifold is constant φ -holomorphic sectional curvature thenwe shall obtain the value of scalar
