beyond". The word Shvetashvatara translates to "the one carrying beyond on white horse" or simply "white mule that carries". The text is sometimes spelled as Svetasvatara Upanishad. It is also known as Shvetashvataropanishad or Svetasvataropanishad, and as Shvetashvataranam Mantropanishad. In ancient and medieval literature, the text is frequently referred to in the plural, that is as Svetasvataropanishadah. Some metric poetic verses, such as Vakaspatyam simply refer to the text as Shvetashva. Chronology The chronology of Shvetashvatara Upanishad, like other Upanishads, is uncertain and contested. The chronology is difficult to resolve because all opinions rest on scanty evidence, an analysis of archaism, style and repetitions across texts, driven by assumptions about likely evolution of ideas, and on presumptions about which philosophy might have influenced which other Indian philosophies. Winternitz, suggests that Svetasvatara Upanishad was probably a pre-Buddha composition along with Katha, Isha, Mundaka and Prasna Upanishad, but after the first phase of ancient Upanishads that were composed in prose such as Brihadaranyaka, Chandogya, Taittiriya, Aitareya, Kaushitaki and Kena. Winternitz states that Isha was likely composed before post-Buddhist Upanishads such as Maitri and Mandukya. Similarly, Phillips chronologically lists Shvetashvatara Upanishad after Mandukya Upanishad, but before and about the time the Maitri Upanishad, the first Buddhist Pali and Jaina canonical texts were composed. Ranade places Shvetashvatara Upanishad's chronological composition in the fourth group of ancient Upanishads, after Katha and Mundaka Upanishads. Deussen states that Shvetashvatara Upanishad refers to and incorporates phrases from the Katha Upanishad, and chronologically followed it. Flood as well as Gorski state that the Svetasvatara Upanishad was probably composed in the 5th to 4th century BCE. Paul Muller-Ortega dates the text between 6th to 5th century BCE. Some sections of the Shvetashvatara Upanishad are found, almost in its entirety, in chronologically more ancient Sanskrit texts. For example, verses 2.1 through 2.3 are also found in chapter 4.1.1 of Taittiriya Samhita as well as in chapter 6.3.1 of Shatapatha Brahmana, while verses 2.4 and 2.5 are also found as hymns in chapters 5.81 and 10.13 of Rig Veda respectively. Similarly, many verses in chapters 3 through 6 are also found, in nearly identical form in the Samhitas of Rig Veda, Atharva Veda and Yajur Veda. Structure The text has six Adhyaya (chapters), each with varying number of verses. The first chapter includes 16 verses, the second has 17, the third chapter contains 21 verses, the fourth is composed of 22, the
