Rig Veda
कृ॒ष्णं त॒ एम॒ रुश॑तः पु॒रो भाश्च॑रि॒ष्ण्व१॒॑र्चिर्वपु॑षा॒मिदेक॑म् । यदप्र॑वीता॒ दध॑ते ह॒ गर्भं॑ स॒द्यश्चि॑ज्जा॒तो भव॒सीदु॑ दू॒तः ॥ कृष्णं त एम रुशतः पुरो भाश्चरिष्ण्वर्चिर्वपुषामिदेकम् । यदप्रवीता दधते ह गर्भं सद्यश्चिज्जातो भवसीदु दूतः ॥
Dark is the path of you wo are bright; the light is before you; your moving radiance is the chief of (all luminous) bodies; when the present (worshippers) take up the germ (in the sticks of attrition) you are speedily genitive rated, and become indeed the messenger (of the sacrifice).
