KAṬHA UPANISHAD · 1.3.10

इन्द्रियेभ्यः परा ह्यर्था अर्थेभ्यश्च परं मनः ।
मनसस्तु परा बुद्धिर्बुद्धेरात्मा महान्परः ॥ १०॥

indriyebhyaḥ parā hyarthā arthebhyaśca paraṃ manaḥ ।
manasastu parā buddhirbuddherātmā mahānparaḥ ॥ 10॥

Than the senses the objects of sense are higher; and higher than the objects of sense is the Mind; and higher than the Mind is the faculty of knowledge; and than that is the Great Self higher.
