In plain words
Without dependence and without support, never an object for any means of knowing, hard to speak of by any comparison, abiding in its own stainless nature, eternal: contemplate this Self every day, and gladly.
Word for word
Gladly contemplate each day the eternally abiding Self, without dependence or support, not an object reached by a means of knowledge, difficult to describe by comparison, and stainless in nature.
