It is by the inner life that self-realization is achieved. Life can be divided into two parts. One part is attending to our worldly needs, toiling, earning money, serving in different capacities in order to have ourselves and to provide for our families. That is one side of life. And the other side is realizing that there is something besides the worldly life, that there is a higher ideal, a greater happiness, a deeper insight into life, and a greater peace. This is another life. By inner life I do not at all mean a religious life; for a man may be religious and at the same time very worldly.
