SB-7.5.23:
śrī-prahrāda uvāca
śravaṇaṁ kīrtanaṁ viṣṇoḥ
smaraṇaṁ pāda-sevanam
arcanaṁ vandanaṁ dāsyaṁ
sakhyam ātma-nivedanam
iti puṁsārpitā viṣṇau
bhaktiś cen nava-lakṣaṇā
kriyeta bhagavaty addhā
tan manye 'dhītam uttamam
Prahlāda Mahārāja said: 1-Hearing and 2-chanting about the transcendental holy name, form, qualities, paraphernalia and pastimes of Lord Viṣṇu, 3-remembering them, 4-serving the lotus feet of the Lord, 5-offering the Lord respectful worship with sixteen types of paraphernalia, 6-offering prayers to the Lord, 7-becoming His servant, 8-considering the Lord one's best friend, and 9-surrendering everything unto Him (in other words, serving Him with the body, mind and words)—these nine processes are accepted as pure devotional service. One who has dedicated his life to the service of Kṛṣṇa through these nine methods should be understood to be the most learned person, for he has acquired complete knowledge.
