Bhagavad Gita 11.54

भक्त्या त्वन्याया शाक्य अहमेवंविधोऽर्जुन |
ज्ञातुं दृष्टुं च तत्त्वेन प्रवेष्टुं च परन्तप

Translation

O Arjun, by unalloyed devotion alone can I be known as I am, standing before you. Thereby, on receiving My divine vision, O scorcher of foes, one can enter into union with Me.
