“Happiness is the nature of the spirit, as stated in the Vedanta-sutras: anandamayo 'bhyasat—the spirit is by nature full of happiness. Happiness in spiritual nature always increases in volume with a new phase of appreciation; there is no question of decreasing the bliss.” (Shrila Prabhupada, Shrimad Bhagavatam, 2.6.18 Purport)
