TheUpanishad includes verses that are partly prayers and benedictions, partly instruction on phonetics and praxis, partly advice on ethics and morals given to graduating students from ancient Vedic gurukula-s (schools), partly a treatise on allegory, and partly philosophical instruction.[3]
Taittiriya is a Sanskrit word that means "from Tittiri". The root of this name has been interpreted in two ways: "from Vedic sage Tittiri", who was the student of Yāska; or alternatively, it being a collection of verses from mythical students who became "partridges" (birds) in order to gain knowledge.[2] The later root of the title comes from the nature of Taittriya Upanishad which, like the rest of "dark or black Yajur Veda", is a motley, confusing collection of unrelated but individually meaningful verses.[2]
The chronology of Taittiriya Upanishad, along with other Vedic era literature, is unclear.[5] All opinions rest on scanty evidence, assumptions about likely evolution of ideas, and on presumptions about which philosophy might have influenced which other Indian philosophies.[5][6]
Stephen Phillips[5] suggests that Taittiriya Upanishad was likely one of the early Upanishads, composed in the 1st half of 1st millennium BCE, after Brihadaranyaka, Chandogya, and Isha, but before Aitareya, Kaushitaki, Kena, Katha, Manduka, Prasna, Svetasvatara and Maitri Upanishads, as well as before the earliest Buddhist Pali and Jaina canons.[5]
Ranade[7] shares the view of Phillips in chronologically sequencing Taittiriya Upanishad with respect to other Upanishads. Paul Deussen[8] and Winternitz,[9] hold a similar view as that of Phillips, but place Taittiriya before Isha Upanishad, but after Brihadaranyaka Upanishad and Chandogya Upanishad.
Some ancient and medieval Hindu scholars have classified the Taittiriya Upanishad differently, based on its structure. For example, Syana in his Bhasya (review and commentary) calls the Shiksha Valli (seventh chapter of the Aranyaka) as Smhit-upanishad, and he prefers to treat the Ananda Valli and Bhrigu Valli (eighth and ninth Prapthakas) as a separate Upanishad and calls it the Vārunya Upanishad.[12]
The Upanishad is one of the earliest known texts where an index was included at the end of each section, along with the main text, as a structural layout of the book. At the end of each Vallĩ in Taittiriya Upanishad manuscripts, there is an index of the Anuvakas which it contains. The index includes the initial words and final words of each Anuvaka, as well as the number of sections in that Anuvaka.[12] For example, the first and second Anuvakas of Shiksha Valli state in their indices that there are five sections each in them, the fourth Anuvaka asserts there are three sections and one paragraph in it, while the twelfth Anuvaka states it has one section and five paragraphs.[12] The Ananda Valli, according to the embedded index, state each chapter to be much larger than currently surviving texts. For example, the 1st Anuvaka lists pratika words in its index as brahmavid, idam, ayam, and states the number of sections to be twenty one. The 2nd Anuvaka asserts it has twenty six sections, the 3rd claims twenty two, the 4th has eighteen, the 5th has twenty two, the 6th Anuvaka asserts in its index that it has twenty eight sections, 7th claims sixteen, 8th states it includes fifty one sections, while the 9th asserts it has eleven. Similarly, the third Valli lists the pratika and anukramani in the index for each of the ten Anuvakas.[12]
The Siksha Valli chapter of Taittiriya Upanishad derives its name from Shiksha (Sanskrit: शक्ष), which literally means "instruction, education".[14] The various lessons of this first chapter are related to education of students in ancient Vedic era of India, their initiation into a school and their responsibilities after graduation.[15] It mentions lifelong "pursuit of knowledge", includes hints of "Self-knowledge", but is largely independent of the second and third chapter of the Upanishad which discuss Atman and Self-knowledge. Paul Deussen states that the Shiksha Valli was likely the earliest chapter composed of this Upanishad, and the text grew over time with additional chapters.[16]
The Siksha Valli includes promises by students entering the Vedic school, an outline of basic course content, the nature of advanced courses and creative work from human relationships, ethical and social responsibilities of the teacher and the students, the role of breathing and proper pronunciation of Vedic literature, the duties and ethical precepts that the graduate must live up to post-graduation.[16][17]
The first anuvaka (lesson) of Taittiriya Upanishad starts with benedictions, wherein states Adi Shankara, major Vedic deities are proclaimed to be manifestations of Brahman (Cosmic Self, the constant Universal Principle, Unchanging Reality).[12][18] Along with the benedictions, the first anuvaka includes a prayer and promise that a student in Vedic age of India was supposed to recite. Along with benedictions to Vedic deities, the recitation stated,[19]
Adi Shankara comments that the "Peace" phrase is repeated thrice, because there are three potential obstacles to the gain of Self-knowledge by a student: one's own behavior, other people's behavior, and the devas; these sources are exhorted to peace.[18]
The second anuvaka highlights phonetics as an element of the Vedic instruction. The verse asserts that the student must master the principles of sound as it is created and as perceived, in terms of the structure of linguistics, vowels, consonants, balancing, accentuation (stress, meter), speaking correctly, and the connection of sounds in a word from articulatory and auditory perspectives.[20] Taittirĩya Upanishad emphasizes, in its later anuvakas, svādhyāya, a practice that served as the principal tool for the oral preservation of the Vedas in their original form for over two millennia. Svādhyāya as a part of student's instruction, involved understanding the linguistic principles coupled with recitation practice of Indian scriptures, which enabled the mastering of entire chapters and books with accurate pronunciation.[21] The ancient Indian studies of linguistics and recitation tradition, as mentioned in the second anuvaka of Taittiriya Upanishad, helped transmit and preserve the extensive Vedic literature from 2nd millennium BCE onwards, long before the methods of mass printing and book preservation were developed. Michael Witzel explains it as follows,[21]
The Vedic texts were orally composed and transmitted, without the use of script, in an unbroken line of transmission from teacher to student that was formalized early on. This ensured an impeccable textual transmission superior to the classical texts of other cultures; it is, in fact, something like a tape-recording.... Not just the actual words, but even the long-lost musical (tonal) accent (as in old Greek or in Japanese) has been preserved up to the present.[21]
The third anuvaka of Shiksha Valli asserts that everything in the universe is connected. In its theory of "connecting links", it states that letters are joined to form words and words are joined to express ideas, just like earth and heavens are forms causally joined by space through the medium of Vayu (air), and just like the fire and the sun are forms causally connected through lightning with the medium of clouds. It asserts that it is knowledge that connects the teacher and the student through the medium of exposition, while the child is the connecting link between the father and the mother through the medium of procreation.[20][22] Speech (expression) is the joining link between upper and lower jaw, and it is speech which connects people.[23]
The structure of the fourth anuvaka is unusual because it starts as a metered verse but slowly metamorphoses into a rhythmic Sanskrit prose. Additionally, the construction of the verse has creative elements that permits multiple translations.[24] The fourth anuvaka is also structured as a liturgical text, with many parts rhythmically ending in Svāhā, a term used when oblations are offered during yajna rituals.[26]
The fifth anuvaka declares that "Bhūr! Bhuvaḥ! Svar!" are three holy exclamations, then adds that Bhur is the breathing out, Bhuvah is the breathing in, while Svar is the intermediate step between those two. It also states that "Brahman is Atman (Self), and all deities and divinities are its limbs", that "Self-knowledge is the Eternal Principle", and the human beings who have this Oneness and Self-knowledge are served by the gods.[27]
The second part of the sixth anuvaka of Shiksha Valli asserts that the "Atman (Self) exists" and when an individual Self attains certain characteristics, it becomes one with Brahman (Cosmic Self, Eternal Reality). These characteristics are listed as follows in verse 1.6.2 :
The seventh anuvaka of Shiksha Valli is an unconnected lesson asserting that "everything in this whole world is fivefold" - sensory organs, human anatomy (skin, flesh, sinews, bones, marrow), breathing, energy (fire, wind, sun, moon, stars), space (earth, aerial space, heavens, poles, intermediate poles).[31] This section does not contextually fit with the sixth or eighth lesson. It is the concluding words of the seventh anuvaka that makes it relevant to the Taittiriya Upanishad, by asserting the idea of fractal nature of existence where the same hidden principles of nature and reality are present in macro and micro forms, there is parallelism in all knowledge. Paul Deussen states that these concluding words of the seventh lesson of Shiksha Valli assert, "there is parallelism between man and the world, microcosm and macrocosm, and he who understands this idea of parallelism becomes there through the macrocosm itself".[32]
The eighth anuvaka, similarly, is another seemingly unconnected lesson. It includes an exposition of the syllable word Om (ॐ, sometimes spelled Aum), stating that this word is inner part of the word Brahman, it signifies the Brahman, it is this whole world states the eight lesson in the first section of the Taittiriya Upanishad. The verse asserts that this syllable word is used often and for diverse purposes, to remind and celebrate that Brahman. It lists the diverse uses of Om in ancient India, at invocations, at Agnidhra, in songs of the Samans, in prayers, in Sastras, during sacrifices, during rituals, during meditation, and during recitation of the Vedas.[31][33]
