Translate the following into Hindi: Poetry is the health and final spirit of all knowledge. Emphatically may it be said of the poet, as Shakespear hath said of man, "he looks before and after." He is the rock of defence for human nature: as upholder and preserver, carrying everywhere with him relationship and love. The poet binds together by passion and knowledge the vast empire of human society. As it is spread over the whole earth, Poetry is the first and last of all knowledge, it is immortal as heart of man. In the study of poetry, therefore, as in the study of all other kinds of literature, our attention must first be directed to the poet himself, to his personality and outlook upon the world, to the interpretation of life expressly given by or held in solution in his work, to the individual note in it. However deeply we may presently become interested in questions of art and form, origins and historical importance, these primary aspects of poetry must never be permitted to slip out of our sight.
