The author has tried to analyse the stand point of "del" (heart) in Rumi's viewpoints. Gnostics pay great attention to "del" which is their device and tool and they look at it and believe that it is God's sight and a manifestation of his glory and elegance and the focus of his grace. Rumi- one of the most important gnostics- believes that "del" is the empyream 'the earth' folcrum of his throne and a lightful sea which is God's manifestation point in both worlds. He also called it (i, e: del) safe city, secure castle and a safe and secure place in which man can rest and be soothed.
