Defining Nine processes of pure devotional service. Importance and glory of each of the processes.
ŚB 7.5.23-24
श्रीप्रह्राद उवाच
श्रवणं कीर्तनं विष्णो: स्मरणं पादसेवनम् ।
अर्चनं वन्दनं दास्यं सख्यमात्मनिवेदनम् ॥ २३ ॥
इति पुंसार्पिता विष्णौ भक्तिश्चेन्नवलक्षणा ।
क्रियेत भगवत्यद्धा तन्मन्येऽधीतमुत्तमम् ॥ २४ ॥

Prahlāda Mahārāja said: Hearing and chanting about the transcendental holy name, form, qualities, paraphernalia and pastimes of Lord Viṣṇu, remembering them, serving the lotus feet of the Lord, offering the Lord respectful worship with sixteen types of paraphernalia, offering prayers to the Lord, becoming His servant, considering the Lord one’s best friend, and 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.
