Explanation:

Kashf-ul-Mahjoob also known as Kashf-ul-Mahjub; is one of the most ancient and admired Persian treatise on Sufism which includes a complete system of Sufism with its practices and doctrines. The author himself a famous Sufi saint who takes an expository approach. Mystical controversies and current opinions are exemplified where many are clarified by presenting his own experiences. The book with its Persian flavour of philosophical speculation is itself a portion of the identity of Abu’l Hasan Ali Hujwiri also known as Data Ganj Baksh. The book has obeyed as a ‘vaseela’, medium of spiritual elevation towards the divinity for various Sufi saints both many of whom were quite famous all over the world. It is because of this reason why Moinuddin Chishti Ajmeri, a chief saint of the Chishti order, once stated that the aspiring murid (disciple) one who doesn’t (yet) have a murshid (spiritual master), must read Ali Hujwiri's book Kashf ul-Mahjoob, as that would (temporarily) guide him spiritually.
