Renunciation made for the sake of service is an ineffable joy of which none can deprive anyone, because that nectar springs from within and sustains life.
When you surrender completely to God, as the only truth worth having, you find yourself in service of all that exists. It becomes your joy and recreation. You never tire of serving others.
Man was made for joy and woe, and when this we rightly know through the world we safely go. Joy and woe are woven fine, a clothing for the soul to bind.
It's always necessary to know when a stage of one's life has ended. If you stubbornly cling to it after the need has passed, you lose the joy and meaning of the rest. And you risk being shaken to your senses by God.
When doubts haunt me, when disappointments stare me in the face, and I see not one ray of hope on the horizon, I turn to Bhagavad-gita and find a verse to comfort me; and I immediately begin to smile in the midst of overwhelming sorrow. Those who meditate on the Gita will derive fresh joy and new meanings from it every day.
