Śrīmad-Bhāgavatam · Text 8.20.34
Who is speaking and story frame
पदं द्वितीयं क्रमतस्त्रिविष्टपं
न वै तृतीयाय तदीयमण्वपि ।
उरुक्रमस्याङ्घ्रिरुपर्युपर्यथो
महर्जनाभ्यां तपस: परं गत: ॥ ३४ ॥
padaṁ dvitīyaṁ kramatas triviṣṭapaṁ
na vai tṛtīyāya tadīyam aṇv api
urukramasyāṅghrir upary upary atho
mahar-janābhyāṁ tapasaḥ paraṁ gataḥ
As the Lord took His second step, He covered the heavenly planets. And not even a spot remained for the third step, for the Lord’s foot extended higher and higher, beyond Maharloka, Janaloka, Tapoloka and even Satyaloka.
