Let M be a compact Sasakian manifold. We show that M admits a CR- embedding into a Sasakian manifold dieomorphic to a sphere, and this embedding is compatible with the respective Reeb fields. We argue that a stronger embedding theorem cannot be obtained. We use an extension theorem for Kahler geometry: given a compact Kahler manifolds X Y , and a Kahler form !X on X which lies in a Kahler class (!) of Y restricted to X, !X can be extended to a Kahler form !Y on Y.
