Bhagavad Gita · 9.13

महात्मानस्तु मां पार्थ दैवीं प्रकृतिमाश्रिताः।भजन्त्यनन्यमनसो ज्ञात्वा भूतादिमव्ययम्॥

mahātmānas tu māṁ pārtha daivīṁ prakṛtim āśhritāḥ bhajanty ananya-manaso jñātvā bhūtādim avyayam

But the great souls, O Partha, who take shelter of My divine nature, worship Me with undivided mind, knowing Me as the imperishable origin of all beings.
