। ॥ ७ ॥
In plain words
For the one who has grown free of body, wealth, children, and wife, whose Buddhi a true Saddeśika, a good teacher, has instructed — for such a one, an unlooked-for Jyotis, whose very Rūpa is Ānanda, arises in samādhi. That, Mother, is Tat tvam asi: you are That, truly.
Close to the Sanskrit
For one detached from body, wealth, offspring, and wife, whose Buddhi has been instructed by a Saddeśika, whatever sudden Jyotis whose Rūpa is Ānanda would arise in samādhi — Tat tvam asi, O Mother, truly.
