Jayapataka Swami: At that time, Prabhupada lived in the grass hut. There was no other place to live in. I remember Prabhupada, one time we were sitting in the grass hut and he just said, “This grass hut is in the mode of goodness, and this is all you need for spiritual life – live in a grass hut and live by the side of the holy river, chant Hare Krishna. But if we do this, people won’t come here. So we have to build the big buildings with concrete and steel and bricks. Those buildings are in the mode of passion. But for preaching, we can build those buildings. But for our own selves, this would be enough.”
