12.4.30

na hi satyasya nānātvam avidvān yadi manyate /
nānātvaṃ chidrayor yadvaj jyotiṣor vātayor iva //

30. There is indeed no difference of Atman, the one true existence and he who believes in difference is one devoid of wisdom; but the difference is a result of conditions as in the case (1) of the sky enclosed by a pot and the unlimited expanse, (2) of the sun shining in the sky and that reflected in water and (3) of the air that is in the body as breath and the air outside in space.
