Rig Veda
आपो॒ न दे॒वीरुप॑ यन्ति हो॒त्रिय॑म॒वः प॑श्यन्ति॒ वित॑तं॒ यथा॒ रज॑: । प्रा॒चैर्दे॒वास॒: प्र ण॑यन्ति देव॒युं ब्र॑ह्म॒प्रियं॑ जोषयन्ते व॒रा इ॑व ॥ आपो न देवीरुप यन्ति होत्रियमवः पश्यन्ति विततं यथा रजः । प्राचैर्देवासः प्र णयन्ति देवयुं ब्रह्मप्रियं जोषयन्ते वरा इव ॥
In like manner, as the bright waters flow to the sacrificial ladle, so they (the gods) look down (upon it); as the diffusive light (descends to earth), the gods convey it, desirous of being presented to them by progressive (movements to the altar), and are impatient to enjoy it, filled with the oblation, as bridegrooms (long for their brides).
