The Eternally Free is verily this Brahman only. He is in the West, in the North and the South, in the Zenith and the Nadir. The Brahman alone is; it is He who pervades all directions. This Brahman alone is it who pervades. This Brahman alone is the Full (that exists in all time the Eternity). This Brahman is the Best:--
This (idam) Brahman is alone the Vis'vam or Infinity or Full (pûrnâm). This alone is the Best, the Highest of all. As the word "idam" is used several times in this verse, it qualifies the word Brahman and not "vis'vam," [Note.--The Brahman was taught to be meditated upon fully in the Heart and the Hiranmaya Kos'a. But lest one should mistake that He is thus limited in those two places, one is to infer that they are selected as the best.]
