And bhāgavata means the book Bhāgavata and the person bhāgavata. The person bhāgavata is spiritual master or any exalted devotee. He is bhāgavata, mahā-bhāgavata, bhāgavata. So bhāgavata-sevayā means not only reading Bhagavad-gītā and Bhāgavatam, but we have to study from the person bhāgavata. That is required. Caitanya Mahāprabhu advised, bhāgavata paṛā giyā bhāgavata-sthāne: "If you want to learn Bhāgavata, then go to the person bhāgavata who is realized soul."
