Upanishads are verses from the Vedas that have been compiled as independent and complete sets. Traditionally the verses in each Veda have been classified as Mantra portion or Brahmana portion. Within the Brahmana portion, a further sub-classification of verses has been done, namely Brahmana-Aranyaka-Upanishad. Upanishad means essential thought or guiding principle.

The Kena Upanishad is attributed to the Samaveda. It attempts to resolve the soul searching Q,
WHAT is it impels me?
Who is directing my senses?
Why is it that I do what I do?
How come I succeed and at times I fail?

This book explains the crux of the verses in easy to grasp contemporary language. It contains original verse in Sanskrit with a Latin
transliteration and an English commentary. Uses clear well-spaced Devanagari font.

tadeva brahma tvaṃ viddhi nedaṃ yadidamupāsate ॥ 1.8
1.8 THAT which doesn't need to breathe, THAT whose creation is the breath; know THAT Brahman to be the breath of this world's beings.
