Rig Veda
पृदा॑कुसानुर्यज॒तो ग॒वेष॑ण॒ एक॒: सन्न॒भि भूय॑सः । भूर्णि॒मश्वं॑ नयत्तु॒जा पु॒रो गृ॒भेन्द्रं॒ सोम॑स्य पी॒तये॑ ॥ पृदाकुसानुर्यजतो गवेषण एकः सन्नभि भूयसः । भूर्णिमश्वं नयत्तुजा पुरो गृभेन्द्रं सोमस्य पीतये ॥
With head uplifted like a serpent, adorable, the recoverer of the cattle, Indra single, is superior tomultitudes; (the worshipper) brings Indra to drink the Soma by a rapid seizure, like a loaded horse (by a halter).
