Rig Veda
ता अ॑त्नत व॒युनं॑ वी॒रव॑क्षणं समा॒न्या वृ॒तया॒ विश्व॒मा रज॑: । अपो॒ अपा॑ची॒रप॑रा॒ अपे॑जते॒ प्र पूर्वा॑भिस्तिरते देव॒युर्जन॑: ॥ ता अत्नत वयुनं वीरवक्षणं समान्या वृतया विश्वमा रजः । अपो अपाचीरपरा अपेजते प्र पूर्वाभिस्तिरते देवयुर्जनः ॥
These dawns diffuse the consciousness that is apprehended by pious men, and (overspread) the whole world with uniform, investing (light); the devout man disregards the dawns which have turned back, and (those which) are to come, and improves (his understanding) by those which have proceeded.
