Bhagavad Gita · 3.42

इन्द्रियाणि पराण्याहुरिन्द्रियेभ्यः परं मनः।मनसस्तु परा बुद्धिर्यो बुद्धेः परतस्तु सः॥

indriyāṇi parāṇy āhur indriyebhyaḥ paraṁ manaḥ manasas tu parā buddhir yo buddheḥ paratas tu saḥ

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 that which is superior to the intellect is the Self.
