The One Manifests as Many
अग्निर्यथैको भुवनं प्रविष्टो
रूपं रूपं प्रतिरूपो बभूव ।
रूपं रूपं प्रतिरूपो बहिश्च ॥ ९॥
agniryathaiko bhuvanaṃ praviṣṭo
rūpaṃ rūpaṃ pratirūpo babhūva .
rūpaṃ rūpaṃ pratirūpo bahiśca .. 9..
As the same non-dual fire, after it has entered the world, becomes different according to whatever it burns, so also the same non-dual Atman, dwelling in all beings, becomes different according to whatever It enters. And It exists also without.
Swami Vivekananda Says —
As fire coming into this world is manifesting itself in various forms, even so, that one Soul of the universe is manifesting Himself in all these various forms.[Source]
