। ॥ ३६ ॥
In plain words
Citta, the mind, becomes sentient through contact with Caitanya, pure consciousness. As a Vṛtti travels from one object to the next, it also crosses the interval between them.
Close to the Sanskrit
Citta, through contact with Caitanya alone, becomes sentient. To go from one object to another, the Vṛtti moves through the interval.
