In the yajurveda , the word uras when changed to uro , retains it original form when followed by a short a which is also retained.,
Thus उरो अन्तरिक्षम् (Yaj. Veda Vajasan. IV. 7). Some read the sutra as यजुष्युरोः ॥ They take the word as उरू ending in उ, which in the Vocative case assumes the form उरो ॥ They give the following example उरो अन्तरिक्षं सजूर् ॥ But in the Yajur Veda VI. II, the text reads उरोरन्तरिक्षम् सजूः ॥ In the Yajur Veda, there being no stanzas, the condition of अन्तः पादं does not apply here.,
