anejad ekam manaso javiyo nainad deva apnuvan purvam arshat
tad dhavato nyan atyeti tishthat tasminn apo matarishva dadhati
The Self is the motionless one, swifter than the mind. The devas (senses) could not overtake it; It ran before them. Sitting, It goes faster than those who run after It. By It, Mātariṣvā (the element Air) supports the activity of all living beings.
From this stanza onwards we have, in four continuous mantras, the description of the Supreme indicated in terms of Its qualities, and these stanzas together is one vākya. Though the Eternal has no quality of Its own, and since language can explain only in terms of guṇas or experiences, the qualities of the Self indicated here are not to be taken literally.
The Upaniṣad asserts that the Self is swifter than the mind. By denying motion, it is not denying the speed which is its rate of motion. The mind is the fastest thing in the universe. But the Self runs faster, because the Reality in the form of ‘existence’ is already there, before the mind could reach the spot of its contemplation.
~Chinmayananda
Anejad means, ‘that which does not move.’ In other words, ‘that Supreme Self does not move’. It is that which is unmoving.
Ekam – ‘One’
Manaso javiyo – ‘Even faster and swifter than the mind.’ If that ‘One’ is faster and swifter than the mind, there is no way that the mind can find It.
Nainad deva apnuvan purvam arshat – ‘There is no way that the senses can ever reach It.’
Tad dhavato nyan atyeti tishthat tasminn apo matarishva dadhati ‘By itself It stands still. It out-strips those who run to reach for It. In It, the all-pervading air or energy – prana, supports the activities of all beings.’
~Sri M
That non-dual Atman, though never stirring, is swifter than the mind. The devas (the senses) cannot reach It, for It moves ever in front. Though standing still, It overtakes others who are running. Because of Atman, Vayu (the World Soul) apportions the activities of all.
VAYU: The first cosmic manifestation of the Absolute in the relative universe, also known by such epithets as the World Soul, Hiranyagarbha, and Prana. It sustains the whole universe by apportioning to everyone his function. But the World Soul can exercise its lordship because Atman is its inner Self. Without Atman even the highest cosmic entity becomes powerless and ceases to exist.
~Nikhilananda
