AITAREYA UPANISHAD · 2.1.3

सा भावयित्री भावयितव्या भवति । तं स्त्री गर्भं बिभर्ति । सोऽग्र एव कुमारं जन्मनोऽग्रेऽधिभावयति । स यत्कुमारं जन्मनोऽग्रेऽधिभावयत्यात्मानमेव तद् भावयत्येषां लोकानां संतत्या एवं संतता हीमे लोकास्तदस्य द्वितीयं जन्म ॥ ३ ॥

sā bhāvayitrī bhāvayitavyā bhavati । taṃ strī garbhaṃ bibharti । so’gra eva kumāraṃ janmano’gre’dhibhāvayati । sa yatkumāraṃ janmano’gre’dhibhāvayatyātmānameva tad bhāvayatyeṣāṃ lokānāṃ saṃtatyā evaṃ saṃtatā hīme lokāstadasya dvitīyaṃ janma ॥ 3 ॥

She the cherisher must be cherished. So the woman beareth the unborn child and the man cherisheth the boy even from the beginning ere it is born. And whereas he cherisheth the boy ere it is born, ’tis verily himself that he cherisheth for the continuance of these worlds and their peoples; for ’tis even thus the thread of these worlds spinneth on unbroken. And this is the second birth of the Spirit.
