Remember the sword of Prema (Love) has to be kept in the sheath of Viveka (Wisdom).  The indriyas (senses) have to be rigorously controlled by Viveka and Vairaagya (discrimination and detachment), the twin talents given exclusively to man.  Viveka instructs you how to choose your avocations and your associates.  It tells you the relative importance of objects and ideals.  Vairaagya saves you from too much of attachment and injects a sense of relief, at times of  elation and despair.  They are the two wings that hold before you the impermanence of the world and the permanence of the Bliss of Reality. They prompt you to direct your lives towards spiritual saadhana and the never failing contemplation of the Glory of the Lord.

- Divine Discourse, July 22, 1958.

Only when one is able to get rid of egoism and attachment can one develop the inner vision. - Baba
