Knowledge itself is the highest end of life and not simply a means to an end. Knowledge is identical with the highest perfection. The sages who have this knowledge are satisfied with It alone and not with some external means of satisfaction which will simply fatten the body and the ego. One’s highest duty consists in the struggle for the attainment of this knowledge by which one gets unified with the all-pervading Absolute Being. This is the same as moksha, where the individuality ceases to be and where one exists in all places and at all times, i.e., becomes infinite and eternal.
