ahaṁ vedmi śuko vetti
vyāso vetti na vetti vā
bhaktyā bhāgavataṁ grāhyaṁ
na buddhyā na ca ṭīkayā
aham - I (Lord Śiva); vedmi - know; śukaḥ - Śukadeva Gosvāmī; vetti - knows; vyāsaḥ - Vyāsadeva; vetti - knows; na vetti vā - or may not know; bhaktyā - by devotional service (executed in nine different processes); bhāgavatam - the Bhāgavata Purāṇa (called the Paramahaṁsa-saṁhitā, the text or treatise readable by the topmost transcendentalists); grāhyam - to be accepted; na - not; buddhyā - by so-called intelligence or experimental knowledge; na - nor; ca - also; ṭīkayā - by imaginary commentary.
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.
