Prabhupada was carrying more than just the duty to execute the order [of his Guru Maharaja]. He was carrying a deep desire to give Krishna and to make Krishna accessible to others. He didn't only want to make them understand. He wanted to awaken their faith, sraddha, and by his own example, he wanted to build that faith from sraddha all the way to prema.
