That which is seen, that which appears to be real, is bound to pass away in the stream of time. All that is apparent in the phenomenal world is bound to disappear sometime or other. We should make every effort to know that which is invisible but imperishable. It is not right that man, who is endowed with immense potencies, should be content with what is seen by the physical eyes. Such eyes are possessed equally by beasts and birds, as well as insects and germs. What then is the uniqueness of the sight given to man? It must be realised that it is difficult to secure human birth. Having acquired this privilege, human beings should not be content with what is seen by the physical eyes. Man should acquire the eyes of wisdom. It may be argued that even the physical eyes help to acquire knowledge. The eyes see everything but cannot see themselves. Eyes which cannot see themselves, how can they see the mind or see Madhava (the Lord)? To have a vision of the Lord, the physical eyes are not competent. One must acquire the eyes of wisdom for this purpose. (Divine Discourse, Oct 22, 1995)
