Kena Upanishad

The Kena Upanishad derives its name from the word 'Kena', meaning 'by whom'. It has four sections, the first two in verse and the other two in prose. The metrical portion deals with the Supreme Unqualified Brahman, the absolute principle underlying the world of phenomenon, and the prose part deals with the Supreme as God, 'Isvara'. The Kena Upanishad concludes, as Sandersen Beck puts it, that austerity, restraint, and work are the foundation of the mystical doctrine; the Vedas are its limbs, and truth is its home. The one who knows it strikes off evil and becomes established in the most excellent, infinite, heavenly world
