Nakiketa, was used as a peg on which to hang the doctrines of the Upanishad. In its original form it may have constituted one Adhyâya only, and the very fact of its division into two Adhyâyas may show that the compilers of the Upanishad were still aware of its gradual origin. We have no means, however, of determining its original form, nor should we even be justified in maintaining that the first Adhyâya ever existed by itself, and that the second was added at a much later time. Whatever its component elements may have been before it was an Upanishad, when it was an Upanishad it consisted of six Vallîs, neither more nor less.
The name of vallî, lit. creeper, as a subdivision of a Vedic work, is important. It occurs again in the Taittirîya Upanishads. Professor Weber thinks that vallî, creeper, in the sense of chapter, is based on a modern metaphor, and was primarily intended for a creeper, attached to the sâkhâs or branches of the Veda?. More likely, however, it was used in the same sense as parvan, a joint, a shoot, a branch, i.e. a division.
Various attempts have been made to distinguish the more modern from the more ancient portions of our Upanishad?. No doubt there are peculiarities of metre, grammar, language, and thought which indicate the more primitive or the more modern character of certain verses. There are repetitions which offend us, and there are several passages which are clearly taken over from other Upanishads, where they seem to have had their original place. Thirty-five years ago, when I first worked at this Upanishad, I saw no difficulty in re-establishing what I thought the original text of the Upanishad must have been. I now feel that we know so little of the time and the circumstances when these half-prose and half-metrical Upanishads were first put together, that I should hesitate

? Though it would be unfair to hold Professor Weber responsible for his remarks on this and other questions connected with the Upanishads published many years ago (Indische Studien, 1853, p. 197), and though I have hardly ever thought it necessary to criticise them, some of his remarks are not without their value even now.
