buddhyā–By means of the intelligence; dhṛti-gṛhītayā–controlled by the yogic practice of dhāraṇā; manaḥ ātma-saṁstham kṛtvā– completely steadying the mind within the self; śanaiḥ śanaiḥ–and gradually; uparamet–as the mind becomes tranquil; na chintayet–one should not think; kiñchit api–of anything else. [25]

By steadying the intelligence, one should gradually still the mind and focus it within the self alone.
