Bhagavad Gita 9.13
But the great souls, O Arjuna! Filled with my divine spirit, they worship me, fix their minds on me alone, for they know that I am the imperishable source of being.
महात्मानस्तु मां पार्थ दैवीं प्रकृतिमाश्रिताः।
भजन्त्यनन्यमनसो ज्ञात्वा भूतादिमव्ययम्॥mahātmānastu māṃ pārtha daivīṃ prakṛtimāśritāḥ|
