CHĀNDOGYA UPANISHAD · 5.1.6
अथ ह प्राणा अहंश्रेयसि व्यूदिरे ।
अहं श्रेयान् अस्म्य् अहं श्रेयान् अस्मीति ॥
atha ha prāṇā ahaṃśreyasi vyūdire ।
ahaṃ śreyān asmy ahaṃ śreyān asmīti ॥
The five senses quarrelled together, who was the best, saying, I am better, I am better.
F. Max Müller · The Upanishads, Sacred Books of the East 1 (1879)
