Isha Upanishad verses 6-8

Those who see all creatures in themselves
And themselves in all creatures know no fear.
Those who see all creatures in themselves
And themselves in all creatures know no grief.
How can the multiplicity of life
Delude the one who sees its unity?

The Self is everywhere. Bright is the Self,
Indivisible, untouched by sin, wise
Immanent and transcendent. He it is
Who holds the cosmos together.

Commentary: The Isha Upanishad invites us to look beyond duality and, beyond the illusion of separate existence, and see the Interbeing of all creation, to see the “Self” everywhere not just in its different forms and facets, but also in its unity.
