Brhadaranyaka Upanisad

The Brhadaranyaka Upanisad belongs to the White Yajurveda. As its name implies, it forms part of an Aranyaka or Forest Teaching, which is attached to the Satapatha Brahmana.

The books are called adhyayas (readings), and the individual chapters brahmanas, reflecting its origin.

OM. That is full; this is full;
Fullness comes forth from fullness:
When fullness is taken from fullness,
Fullness remains.

OM. Peace, peace, peace.
