खं वायुमग्निं सलिलं महीं च
ज्योतींषि सत्त्वानि दिशो द्रुमादीन् ।
सरित्समुद्रांश्च हरेः शरीरं
यत्किं च भूतं प्रणमेदनन्यः ॥
– श्रीमद् भागवतम् ११.०२.४१

khaṃ vāyum-agniṃ salilaṃ mahīṃ ca
jyotīṃṣi sattvāni diśo drumādīn ।
sarit-samudrāmśca hare: śarīraṃ
yat-kiñ-ca bhūtaṃ praṇamed-ananya: ।।
– Śrīmadbhāgavatam 11.2.41

Space, wind, fire, water, earth, all the celestial objects, all the living creatures, the directions, trees, plants and other immovable beings, as well as the rivers and the oceans form the body of Lord Hari. So, (with one-pointed devotion) prostrate before every being (regarding that to be Lord Hari).
