Śrīmad-Bhāgavatam · Text 5.18.31
Who is speaking and story frame
यद्रूपमेतन्निजमाययार्पित-
मर्थस्वरूपं बहुरूपरूपितम् ।
सङ्ख्या न यस्यास्त्ययथोपलम्भनात्-
तस्मै नमस्तेऽव्यपदेशरूपिणे ॥ ३१ ॥
yad-rūpam etan nija-māyayārpitam
artha-svarūpaṁ bahu-rūpa-rūpitam
saṅkhyā na yasyāsty ayathopalambhanāt
tasmai namas te ’vyapadeśa-rūpiṇe
My dear Lord, this visible cosmic manifestation is a demonstration of Your own creative energy. Since the countless varieties of forms within this cosmic manifestation are simply a display of Your external energy, this virāṭ-rūpa [universal body] is not Your real form. Except for a devotee in transcendental consciousness, no one can perceive Your actual form. Therefore I offer my respectful obeisances unto You.
