BṚHADĀRAṆYAKA UPANISHAD · 6.1.7

ते हेमे प्राणा अहंश्रेयसे विवदमाना ब्रह्म जग्मुः ।
तद् धोचुः -- को नो वसिष्ठ इति ।
तद् धोवाच -- यस्मिन् व उत्क्रान्त इदं शरीरं पापियो मन्यते स वो वसिष्ठ इति ॥

te heme prāṇā ahaṃśreyase vivadamānā brahma jagmuḥ ।
tad dhocuḥ -- ko no vasiṣṭha iti ।
tad dhovāca -- yasmin va utkrānta idaṃ śarīraṃ pāpiyo manyate sa vo vasiṣṭha iti ॥

These Prânas (senses), when quarrelling together as to who was the best, went to Brahman and said: 'Who is the richest of us?' He replied: 'He by whose departure this body seems worst, he is the richest.'
