Upanisad-s are the philosophical portion of the veda-s.

Its poetic diction, systematic development of thought-at once clear, concise and scientific in arrangement of highly philosophical ideas make Kaivalya Upanisad one the most striking minor Upanisad-s.

The great commentator Narayana calls the Kaivalya Upanisad as the Brahma- Satarudriya i.e. the Satarudriya which glorifies the unconditioned Brahman as opposed to the Personal God, Lord Siva of the original Satarudriya.

True to the Upanisadik style where story form is considered as the most apt devise to make the subject easily intelligible to the readers, in this Upanisad Asvalayana, the great teacher of Rg Veda is a disciple and Lord Brahma, the Creator himself is the teacher, which makes this as the most valuable amongst the 'minor' Upanisad-s.
