Rig Veda
किय॑त्स्वि॒दिन्द्रो॒ अध्ये॑ति मा॒तुः किय॑त्पि॒तुर्ज॑नि॒तुर्यो ज॒जान॑ । यो अ॑स्य॒ शुष्मं॑ मुहु॒कैरिय॑र्ति॒ वातो॒ न जू॒तः स्त॒नय॑द्भिर॒भ्रैः ॥ कियत्स्विदिन्द्रो अध्येति मातुः कियत्पितुर्जनितुर्यो जजान । यो अस्य शुष्मं मुहुकैरियर्ति वातो न जूतः स्तनयद्भिरभ्रैः ॥
Some portion (of his strength) Indra derives from his mother, some portion from his father; he who, though his progenitor, has begotten (the world), and animates its vigour repeatedly, as the wind is driven by thundering clouds.
