। ॥ ३७ ॥
In plain words
The state that leans on nothing and changes into nothing — that is the one they call unmanī, mind gone past mind. And take the 'ta' out of citta: know the mind, when that syllable is gone, as cit — consciousness itself.
Close to the Sanskrit
That state which is without support and without modification — that is called unmanī. One should know citta as cit, when it is devoid of the letter 'ta'.
