व्याप्ते मे रोदसी पार्थ क्रान्तिश्चाभ्यधिका स्थिता ।क्रमणाच्चाप्यहं पार्थ विष्णुरित्यभिसंज्ञितः ॥
In plain words
Heaven and earth — both are filled by me, Arjuna, and my stride reaches further still. Because of that striding, Arjuna, I am called Viṣṇu.
Close to the Sanskrit
By me, O Pārtha, heaven and earth are pervaded, and my striding stands surpassing them; and because of that striding also, O Pārtha, I am designated 'Viṣṇu'.
