Katha Upanishad Verse 2.1.11

Following the previous verse’s warning against perceiving duality, this verse explains that the non-dual reality is attained through a purified and focused mind. It reiterates that there is no actual difference or multiplicity “here” (in reality), and that the illusion of difference leads back into the cycle of death.
