इन्द्रियाणि पराण्याहुरिन्द्रियेभ्यः परं मनः। मनसस्तु परा बुद्धिर्यो बुद्धेः परतस्तु सः॥
indriyani parany ahur indriyebhyah param manah manasas tu para buddhir yo buddheh paratas tu sah
Translation
The senses are said to be superior to the body, the mind is superior to the senses, the intellect is superior to the mind, and the self is superior to the intellect.
Commentary
Krishna maps the hierarchy of being: body, senses, mind, intellect, and finally the self (atman). Each higher level controls the one below it. The self, being supreme, can control everything when properly awakened.
