3.10.8.10

ātmā́ hṛ́daye /
hṛ́dayaṃ máyi /
ahám amṛ́te /
amṛ́taṃ bráhmaṇi //
púnar ma ātmā́ púnar ā́yur ā́gāt /
púnaḥ prāṇáḥ púnar ā́kūtam ā́gāt /
vaiśvānaró raśmíbhir vāvṛdhānáḥ /
antás tiṣṭhatv amṛ́tasya gopā́ḥ //

the self in the heart; / the heart in me; / I in the immortal; / the immortal in the sacred word. / Again has my self, again has my lifespan returned; / again has my breath, again has my intent returned. / May Vaiśvānara, growing strong through his rays, / stand within as guardian of immortality.
