11.7.47

स्वमायया सृष्टमिदं सदसल्ल‍क्षणं विभु: । प्रविष्ट ईयते तत्तत्स्वरूपोऽग्निरिवैधसि ॥ ४७ ॥

sva-māyayā sṛṣṭam idaṁ sad-asal-lakṣaṇaṁ vibhuḥ praviṣṭa īyate tat-tat- svarūpo ’gnir ivaidhasi

sva-māyayā
by His own material energy
sṛṣṭam
created
idam
this (body of the individual jīva)
sat-asat
as demigod, animal, and so on
lakṣaṇam
characterized
vibhuḥ
the Almighty
praviṣṭaḥ
having entered
īyate
appears
tat-tat
of each different form
svarūpaḥ
assuming the identity
agniḥ
fire
iva
as
edhasi
in firewood

Just as fire manifests differently in pieces of wood of different sizes and qualities, the omnipotent Supreme Soul, having entered the bodies of higher and lower life forms created by His own potency, appears to assume the identity of each.
