There are nine items to be executed in devotional service. These are enumerated in the following verse from ÅšrÄ«mad-BhÄgavatam (7.5.23):
Å›ravaṇaá¹ kÄ«rtanaá¹ viṣṇoḥ smaraṇaá¹ pÄda-sevanam
arcanaá¹ vandanaá¹ dÄsyaá¹ sakhyam Ätma-nivedanam
Hearing the glories of the Lord, chanting, remembering, serving the lotus feet of the Lord, offering worship in the temple, offering prayers, becoming a servant of the Lord, becoming the Lord’s friend, and sarvÄtma-nivedana, offering oneself fully at the lotus feet of the Lord — these are the nine devotional processes. In The Nectar of Devotion, these are expanded into sixty-four items. When SÄrvabhauma Bhaá¹á¹ÄcÄrya asked the Lord which item was most important, ÅšrÄ« Caitanya MahÄprabhu immediately answered that the most important item is the chanting of the holy names of the Lord — Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare RÄma, Hare RÄma, RÄma RÄma, Hare Hare. He then quoted the following verse from the Bá¹›han-nÄradÄ«ya PurÄṇa (thirty-eighth chapter, verse 126) to confirm His statement.
