In plain words
Of all the intellect's states, none is set harder than this one: 'I am the body,' and the rest of it. And that notion plainly belongs to ahaṅkṛti, the I-making. So counting the ego in here is exactly right.
Close to the Sanskrit
In the body and the rest, the notion 'I' alone is seen to be the very firmest state of the intellect, belonging to the I-making faculty; therefore its inclusion here is fitting.
