"Spiritual happiness is anandambudhi-vardhanam, or the ocean of happiness which increases. The material ocean is stagnant, but the spiritual ocean is dynamic. In the Caitanya-caritamrta, (Adi-lila, Fourth Chapter) Kaviraja Gosvami has very nicely described this dynamic increment of the ocean of spiritual happiness in the transcendental person of Srimati Radharani, the pleasure potency of Lord Krsna."
