Kena Upanisad consists of the the four sections of the fourth chapter of the Jaiminiya Brahmana Upanisad of the Samaveda. It begins directly with Brahman as its subject matter and tells us in first two parts how it is impossible to know or attain Brahman by our ordinary senses including mind. To realize Brahman we have to open ourselves to higher intuitive levels of mind. In the third and fourth parts, the Upanisad beautifully speaks about the unknowable Brahman and about the subjective and objective ways of its realization through an allegorical story about Gods led by Indra on one side and Yaksha and Uma Haimvati on the other. Brahman has to be meditated upon and realized as Tad Vanam that most delightful dear one.
