The Kena Upanishad is so named because it asks many fundamental questions that begin with the phrase, “by whom” – or “kena”. By whom willed and directed does the mind alight upon objects of the world?

In conjunction with Chapter 8 of the Gita, it forms a pillar of the knowledge of the One supreme reality. The Kena addresses both the impersonal and personal aspects of Brahman, so as to engage the needs of all levels of truth-seekers.
