''It Is What It Is" or "In It What Is in It'') is a Persian prose work of 13th century Sufi mystic and Iranian poet Jalāl al-Dīn Muḥammad Rūmī.
Rumi himself in the fifth volume of Masnavi-i Ma'navi mentions[2] that which most likely refers to this book.
According to B. Forouzanfar, the editor of the most reliable copy of the book, it is likely that the book was written by Sultanwalad, the eldest son of Rumi, based on manuscripts and notes taken by himself or others from the lectures of his father on Masnavi-i Ma'navi.
A more recent translation into English, with commentary for each of the discourses, by Doug Marman (with the assistance of Jamileh Marefat, a direct descendant of Rumi) was published in 2010 under the title It Is What It Is, The Personal Discourses of Rumi (Spiritual Dialogues Project, Ridgefield, Washington), ISBN 978-0-9793260-5-9.
Thackston, Jr, was published in 1994 under the title 'Signs of the Unseen: The Discourses of Jalaluddin Rumi' (Putney, VT: Threshold Books, 1994; republished by Shambhala Publications, 1999).
