Shvetashvatara Upanishad 1.15-1.16

As oil in sesame seeds,

as butter in milk,

as water in Srota,[36]

as fire in fuel-sticks,

he finds in his own self that One (Atman), he,

who sees him through Satya (truthfulness)

and Tapas (austerity).

He sees the all pervading Atman,

as butter lying dormant in milk,

rooted in self-knowledge and self-discipline

– which is the final goal of the Upanishad,

the final goal of Upanishad.
