सततं कीर्तयन्तो मां यतन्तश्च दृढव्रताः। नमस्यन्तश्च मां भक्त्या नित्ययुक्ता उपासते ॥

satataṁ kīrtayanto māṁ yatantaśh cha dṛiḍha-vratāḥ namasyantaśh cha māṁ bhaktyā nitya-yuktā upāsate

Always magnifying Me, strenuous, firm in vows, prostrating themselves before Me, they worship Me with devotion ever harmonised.

In plain words: Krishna says these devoted people always praise him. They work hard, keep their promises, and bow down to him. Their worship is full of love and they stay steady in it.
