“Without doubt, whenever you sit with someone and are with him, you will take on his disposition. On whom have you been gazing that tightness should have come into you? If you look at green herbs and flowers, freshness will come. The sitting companion pulls you into his own world. That is why reciting the Koran purifies the heart, for you remember the prophets and their states. The form of the prophets comes together in your spirit and becomes its sitting companion.” – Shams-i-Tabrizi
