چکیده (انگلیسی): A way to recognize things is putting a question to their essence which on the veiew of logicians is well known by nominal essence and “real essence”. Whatness of theosophy is argued and considered from various perspective like literal, terminological, narrative and Quranic point of view in this investigation. And the end is presentation a true and exact deduction from differnet definitions and explantions of theosophy. Because it has been an argument for motakalims, philosophers and Ghostics, study of thses sages points of view have an improtant role for students about theosophy recognition. The study and learning of theosophy is also enforced and encouraged as a duty with many benefits on Quranic and tradition discources of prophet of Islam and his household. So thinkers of different schools believe their method is sole true method on perception of theosophy and methods of other rivals are false. They, therefore, have been created extensive arguments for researchers which is considered in this investigation. In addiotion to presentation of comprehensive and complete recognition of theosophy, then it’s argued and considered that how does theosophy receive and what are benefits, losses and barriers of its way. In addition to study of different ideas and schools and compare between them, in this investiagion divine Gnosticists is perceived as comprehensive and prevaling method between various perspectives and behave on their way is choosed as true way on obtaining theosophy and truth. Acknowledging and admiting of Motakalims and philosophers like Abu Hamed Qazali and Avecina is famous in thid field. Tendency to these scientists to Gnosticism is a strict demonestration for this claim. Another part of this investigation consists of theosophy evolution from beginning of Islam to end of Sabzevar school. Islamic thinkers especially shiites took serious and immense sprituall struggle against in crustive and superfiscal thouths of different external and internal schools. Their goal was taking a disginction betwee divine and true theosophy from anothers. It’s the reason of relationship between this part and the part of theosophy essence.
