Verse 11

11. The sheaths, essence etc. that are indeed expounded in the Taittirlyaka Upanishad of them, the supreme Jiva is clearly shown up as Atman, like Akasa.

The sheaths expounded in the Taittiriya Upanishad describe the forms of Maya that shroud the jiva or true being or the Self giving the illusion of individuality. The outer sheath being the gross form, made up of food. But as we have been shown here these sheaths are forms only, Like clay pots they are empty of any true existence other than the Absolute Self which in truth is the form itself, the space within the form, the space without the form. The appearance of individuals existing and moving in the space or void or Akasa of creation is the illusion because this existence of space is itself the projection of the Absolute self. Whatever further objects or beings that appear to exist on top of, or in that space are as clay pots or balloons floating in the air only the clay pots or balloon, or the sheath itself, is an illusion or Maya. The air, or the void, or the Akasa is mentioned for description only, to represent the Self. But The Self alone exists all else is an illusion supported by the existence of The Self.
