Desire, awareness of the Self and action all are manifestation of the same energy that is you. Among these three, one of them dominates at a time. When you have lots of desires, you are not aware of the Self. When desire dominates, Self-awareness will be at its lowest, and that's why all the philosophers around the world have always advocated renunciation and dropping of desires. When the awareness is dominant, then happiness dawns. When desire dominates, stress and sorrow result. When actions dominates, restlessness and disease is the result. When your actions and desires are sincerely directed to the Divine or to the welfare of society, then the consciousness is automatically elevated, and Self - knowledge is sure to be attained.
