Now then and therefore, the author’s aim is to recover the full ancient Aruneya Upanishad from the parts that are scattered in the other Upanishads. The author humbly attempts no more than to restore the deep insights, such as it must have existed at the time within the Self of Uddalaka Aruna and son Aruni but to gain an approximate conception of what the original composer may have had insightfully gained, before handing his composition over to the safekeeping of oral tradition past down the lineage of Gotama.
