In plain words
It is not something fit to be thought of, and yet it is not beyond contemplation. It is not thought, and yet it is thought itself. Always contemplate the supreme Self, which leans to no side at all.
Word for word
Always contemplate the supreme Self, inclining to neither side: it is not an object of thought, yet not inaccessible to contemplation; it is not thought, yet is itself the reality of thought.
