ŚVETĀŚVATARA UPANISHAD · 4.5

अजाम् एकां लोहितशुक्लकृष्णां बह्वीः प्रजाः सृजमानां सरूपाः ।
अजो ह्य् एको जुषमाणो ऽनुशेते जहात्य् एनां भुक्तभोगाम् अजो ऽन्यः ॥

ajām ekāṃ lohitaśuklakṛṣṇāṃ bahvīḥ prajāḥ sṛjamānāṃ sarūpāḥ ।
ajo hy eko juṣamāṇo ’nuśete jahāty enāṃ bhuktabhogām ajo ’nyaḥ ॥

There is one unborn being (female), red, white, and black, uniform, but producing manifold offspring. There is one unborn being (male) who loves her and lies by her; there is another who leaves her, while she is eating what has to be eaten.
