US-P18.174ab ।US-P18.174cd ॥
In plain words
"You are the tenth" — it works just like that. From "tat tvam asi" and the sentences like it, a person comes to know his own ātman: the seeing in which the whole of the mind is seen.
Close to the Sanskrit
'You are the tenth' — thus, from the sentence 'That thou art' and the rest, one thoroughly knows one's own Self, the seeing of the entire inner organ.
