12.4.22

लय: प्राकृतिको ह्येष पुरुषाव्यक्तयोर्यदा । शक्तय: सम्प्रलीयन्ते विवशा: कालविद्रुता: ॥ २२ ॥

layaḥ prākṛtiko hy eṣa puruṣāvyaktayor yadā śaktayaḥ sampralīyante vivaśāḥ kāla-vidrutāḥ

layaḥ
the annihilation
prākṛtikaḥ
of the material elements
hi
indeed
eṣaḥ
this
puruṣa
of the Supreme Lord
avyaktayoḥ
and of His material nature in its unmanifest form
yadā
when
śaktayaḥ
the energies
sampralīyante
merge totally
vivaśāḥ
helpless
kāla
by time
vidrutāḥ
disarrayed

This is the annihilation called prākṛtika, during which the energies belonging to the Supreme Person and His unmanifest material nature, disassembled by the force of time, are deprived of their potencies and merge together totally.
