(Srila Prabhupada at the Bhaktivedanta Manor, 1973)
"We can guarantee you will be happy. Yes. Hare Kṛṣṇa. Our Vedic mission is sarve sukhino bhavantu: everyone be happy. This is our mission. And we know how to become happy. That is our credit.
We know. How to become happy, we know. Therefore, you can inform others also how to become happy. Happiness is our birthright. Ānandamayo 'bhyāsāt. Living entity is ānandamaya, full of happiness, but they have fallen in a different condition.
Therefore unhappy. Different condition. Just like fish taken out of the water and put into the land, a different condition, and it is throbbing, flapping, unhappy. Take it, put it in the water again, and it will be happy. That's it."
