येषां वृत्तिः समावृद्धा परिपक्वा च सा पुनः ।ते वै सद्ब्रह्मतां प्राप्ता नेतरे शब्दवादिनः ॥ १३२ ॥
In plain words
Those in whom this one thought has grown until it fills the whole mind, and then ripened — they, and only they, have become the real Brahman. Not the others. The others are still talking about words.
Close to the Sanskrit
Those in whom the vṛtti has grown fully, and in whom that same vṛtti has further ripened — they indeed have attained the state of being the real Brahman; not the others, who are speakers of words.
