त्वमादिदेवः पुरुषः पुराणस्त्वमस्य विश्वस्य परं निधानम्।वेत्तासि वेद्यं च परं च धामत्वया ततं विश्वमनन्तरूप॥

tvamādidevaḥ puruṣaḥ purāṇastvamasya viśvasya paraṃ nidhānam |vettāsi vedyaṃ ca paraṃ ca dhāmatvayā tataṃ viśvamanantarūpa ||

You are the primal God, the ancient Purusha, the supreme refuge of this universe, the knower, the knowable, and the supreme Abode. Through You, the universe is pervaded, O Being of infinite forms.

You are the Primal God, the Ancient One, the Supreme Abode of this universe, the Knower, the Knowledge, and the Final Home. You fill everything. Your form is infinite.
