11.19.16

आदावन्ते च मध्ये च सृज्यात् सृज्यं यदन्वियात् । पुनस्तत्प्रतिसङ्‍क्रामे यच्छिष्येत तदेव सत् ॥ १६ ॥

ādāv ante ca madhye ca sṛjyāt sṛjyaṁ yad anviyāt punas tat-pratisaṅkrāme yac chiṣyeta tad eva sat

ādau
in the causal stage
ante
in the termination of the causal function
ca
also
madhye
in the phase of maintenance
ca
also
sṛjyāt
from one production
sṛjyam
to another production
yat
which
anviyāt
accompanies
punaḥ
again
tat
of all material phases
pratisaṅkrāme
in the annihilation
yat
which
śiṣyeta
remains
tat
that
eva
indeed
sat
the one eternal

Commencement, termination and maintenance are the stages of material causation. That which consistently accompanies all these material phases from one creation to another and remains alone when all material phases are annihilated is the one eternal.
