When the Understanding desires anything, it is called by the name of Mind. The senses, again, should all be considered as contained within the Understanding. The senses, which are engaged in bearing impressions of form, scent, etc., should all be controlled.
यदा प्रार्थयते किंचित् तदा भवति सा मनः। अधिष्ठानानि वै बुद्ध्यां पृथगेतानि संस्मरेत्। इन्द्रियाण्येव मेध्यानि विजेतव्यानि कृत्स्नशः॥
