Not that “Now I am free from family life, I have no responsibility. Now I shall take prasadam and sleep.” No. That is not. [laughs] You must be hundred times more active than in your family life. That is devotional service. Of course, it is not pride, but take from example of my life. I was retired in Vrndavana, and at seventy years old I thought that it was to be done: “Nobody did it. Let me try.” So I came to your country. Today is the tenth anniversary. [devotees cheer] So at least from material calculation, if I would not have taken that risk… When I was coming, my friends and others said, “This man is going to die.” “Never mind,” I thought. “Death will come. Let me try.” So this activity must be there. That is the begging of Sanatana Gosvami, that he said, apana-krpate kaha ‘kartavya’ amara: “What shall I do?” Doesn’t matter what is your age, young man or old man. You must execute the order of the Supreme Personality of Godhead, parampara, Caitanya Mahaprabhu and your guru. That is real life of devotional service, to take some responsibility for working and execute it to your best capacity.
