Ishadi Nau Upanishad is a compilation of nine principal Upanishads presented with their original Sanskrit text and an accompanying Hindi commentary, published by Gita Press, Gorakhpur.

The Upanishads are foundational texts of Vedanta philosophy, dealing with the nature of the self (atman), the ultimate reality (Brahman), and the path to liberation (moksha); this volume brings together nine of the principal Upanishads, beginning with the Isha Upanishad, in one book, making them accessible for sequential study.

Usage: This book is generally used for serious scriptural study by readers interested in Vedanta philosophy, either read section by section over time or used as a reference alongside discourses (pravachan) on the Upanishads.

Ritual/Occasion Context: Study of the Upanishads is traditionally undertaken as part of svadhyay (personal scriptural study) and is commonly pursued during Chaturmas or under the guidance of a teacher (guru) in a structured learning setting.
