But there is one thing that can never become stale to you — 'Joy' itself.
Happiness that is delightfully varied, though its essence is changeless, is the inner experience everyone is seeking. 'Lasting, Ever New Joy Is God'. Finding this Joy within, you will find it in everything without. In God you will tap the Reservoir of perennial, unending 'Bliss'.
Excerpts from the writings of Sri Paramahansa Yogananda
