The works of Ādi Śaṅkarācārya

Viṣṇusahasranāmastotram

Verse 92

सकलमिदमहं च वासुदेवः परमपुमान्परमेश्वरः स एकः ।इति मतिरचला भवत्यनन्ते हृदयगते व्रज तान्विहाय दूरात् ॥

In plain words

All of this and I are Vasudeva—the supreme spirit, the supreme lord, the one without a second. When this conviction is unshakably established in the heart with the infinite, leave all else far behind.

Close to the Sanskrit

All this and I are Vasudeva, the supreme person, the supreme lord, He is one. Thus when the infinite is in the heart, the conviction becomes steadfast; abandon those things from afar.
