Devotional service includes nine processes, beginning with hearing, chanting and remembering the activities of Lord Viṣṇu. Only one who has taken to devotional service can understand Śrīmad-Bhāgavatam, which is the spotless Purāṇa for a transcendentalist (paramahaṁsa). So-called commentaries are useless for this purpose. According to the Vedic injunction, yasya deve parā bhaktir yathā deve tathā gurau. All Vedic literatures maintain that Śrīmad-Bhāgavatam has to be learned from the person bhāgavata, and to understand it one has to engage in pure devotional service. Śrīmad-Bhāgavatam cannot be understood by so-called erudite scholars or grammarians. One who has developed pure Kṛṣṇa consciousness and has served the pure devotee, the spiritual master, can understand Śrīmad-Bhāgavatam. Others cannot.
