Bhagavad-gita As It Is Lectures

These are nine kinds of services. They are sat. The more we are engaged in these nine kinds of different occupation of devotional service, the more we are elevated.

Lecture on BG 2.16 -- London, August 22, 1973:

Now what is Kṛṣṇa's service? That we are teaching, how to worship Kṛṣṇa.

śravaṇaṁ kīrtanaṁ viṣṇoḥ

smaraṇaṁ pāda-sevanam

arcanaṁ vandanaṁ dāsyaṁ

sakhyam ātma-nivedanam

(SB 7.5.23)

These are nine kinds of services. They are sat. The more we are engaged in these nine kinds of different occupation of devotional service, the more we are elevated, and the more we are engaged in activities of material sense gratification, we are degraded. Śrama eva hi kevalam (SB 1.2.8).
