Understand this great truth: The happiness that comes from the pleasures of the world is but a minute reflection of the infinite bliss that comes from within your own Self.
The agony caused by the longing to see God is not sorrow; it is bliss. The state that we attain by calling and crying to God is equal to the bliss that the yogi experiences in samadhi.
True happiness is when the love that is within us finds expression in external activities.
