Aitareyopaniṣad is an upaniṣad which is a part of the Aitareya āraṇyaka. It is traditionally associated with the Ṛgveda saṃhitā. The text explores the nature of the Ātman (self) and it's connection to the Paramātmā (universal self). The text is included in the ten upaniṣads on which the original Śaṅkarācāryas bhāṣya is available making it an authentic Vedic upaniṣad not medieval. It is an important text for the Advaita(non-dualistic) Vedānta philosophical tradition. The Aitareya upaniṣad is divided into three adhyāyas (chapters) which are the 4th, 5th and 6th chapters of the 2nd Āraṇyaka (book) of the Aitareya Āraṇyaka. [1](f. 1a–4b), [2](f. 4b–7b), [3](f. 6a–6b). There is a Śāntipāṭha in the Begining (f. 1a) and end (f. 6b–7a) of the text. This Ms. is written in 7 lines per folio. Title present in the begining (f. 1a). Mistakes are covered with yellow or blacked out. Some corrections and additions in the margins. Significant syllables and words rubbed with orange powder for highlighting.
