Whatever responsibilities you take on in this stage of your life, if you make kirtan—especially kirtan in the association of devotees who have a taste for it—an integral part of your life, you will become very dear to Srila Prabhupada. Srila Prabhupada came to give us the pure holy name, imbued with the full rasa of ecstatic love for Krishna. I cannot think of anything that could make Srila Prabhupada smile more than to see his followers, for many generations to come, relishing the taste of the pure holy name.
