Keshava is such. More than this. He is Narayana, the highest of the high, immutable and undecaying. He is the cternal and changeless cause of the entire mobile and immobile universe with its beginning, middle, and end, as also of all creatures whose birth follows their wish.
एतादृशः केशवाऽतश्च भूयो नारायणः परमश्चाव्ययश्च। मध्याद्यन्तस्य जगतस्तस्थुषश्च बुभूषतां प्रभवश्चाव्ययश्च॥
