It is not that we need more knowledge about the mind as much as finding how to construct a life- saving bridge from our minds to the knowledge deep in our hearts.
Stranded on the shores of knowledge of the intellect alone, we eventually find ourselves lonely and devoid of real life satisfaction and experience regardless of our accumulation of information.
If we should choose to depend upon our emotions and consciousness of our hearts alone, we soon learn that we need the mind to channel our affections and sympathies appropriately.
