In plain words
I am not gross, not subtle, and not a void. I am the world's kinsman, made of knowledge. I am eternal, the Lord, without stain, free of the long succession of states, and the spread of the world is not in me.
Word for word
I am neither gross, subtle nor void. I am the world's friend, of the nature of knowledge, eternal, Lord and stainless, without conditioned states or phenomenal proliferation.
