यत्र यत्र मनो याति ब्रह्मणस्तत्र दर्शनात् ।मनसो धारणं चैव धारणा सा परा मता ॥ १२२ ॥
In plain words
Wherever the mind runs, Brahman is what it sees there — and holding the mind in that seeing is the highest concentration there is.
Close to the Sanskrit
Wherever, wherever the mind goes, there, because of the vision of Brahman, the holding of the mind — that indeed is considered the supreme dhāraṇā.
