AVŚ 9.10.19
ऋचः पदं मात्रया कल्पयन्तो ऽर्धर्चेन चक्ळ्पुर् विश्वम् एजत् । त्रिपाद् ब्रह्म पुरुरूपं वि तष्ठे तेन जीवन्ति प्रदिशश् चतस्रः ॥१९॥
ṛcaḥ padaṃ mātrayā kalpayanto 'rdharcena cakḷpur viśvam ejat | tripād brahma pururūpaṃ vi taṣṭhe tena jīvanti pradiśaś catasraḥ ||19||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Shaping (kalpay-) with measure the step of the verse, they shaped by the half-verse all that stirs; the bráhman of three feet, many-formed, spread out (vi-sthā); by that do the four quarters live.
Translated by William Dwight Whitney (1905)
