Bhagavad Gita 9.14 — Singing and bowing
सततं कीर्तयन्तो मां यतन्तश्च दृढव्रताः। नमस्यन्तश्च मां भक्त्या नित्ययुक्ता उपासते ॥
satataṃ kīrtayanto māṃ yatantaśca dṛḍhavratāḥ | namasyantaśca māṃ bhaktyā nityayuktā upāsate ||
Meaning
Always singing my glories, striving with firm vows, and bowing to me in devotion, they worship me ever united.
