अथ खलु व्यानमेवोद्गीथमुपासीतयद्वै प्राणिति स प्राणो यदपानिति सोऽपान ।अथ य प्राणापानयो सधिः स व्यानो यो व्यान सा वाक् ।तस्मादप्रा- णन्नपानन्वाचमभिव्याहरति ॥ ३ ॥
In plain words
Now, let a person meditate on Vyāna alone as the Udgītha. That which moves outward is Prāna; that which moves inward is Apāna. The junction where Prāna and Apāna meet is Vyāna; and that Vyāna is speech itself. Therefore, without actively moving either Prāna or Apāna, one utters speech.
Close to the Sanskrit
Now indeed one should meditate upon Vyana alone as the Udgitha. That which breathes forth is Prana; that which breathes down is Apana. Now that which is the junction of Prana and Apana is Vyana; that which is Vyana is Speech. Therefore, without breathing forth and without breathing down, one utters speech.
