Maulana Rumi (R.A.) says: "It is completely useless to swim about in the sea of Reason and intellect. There is need for the ship of Nabi Nooh (A.S.) - i.e. The help of the friends of Allah. Look how Nabi Nooh's (A.S.) son - Kan'aan depended on Reason alone saying: "The high mountains shall save me from this storm". He considered the ark of Nabi Nooh (A.S.) as being despicable. The result was that the ship was saved during the deluge and reached the high mountain while Kan'aan was drowned.
Maulana Rumi (R.A.) says: "When you do not look with proper sight, then you look upon the love and company of the saintly ones and their obedience i.e. their ship as despicable, and you look upon your imitation of the people of Europe as the high mountains of Intellect and Reason. But, beware, do not look upon this ship as being of no value and a thing to be despised.It is true that the Ah-Iullah, the saints are usually dressed in old and tattered clothes and live simple lives, but do not look at the simplicity of their lives and consider them lowly and despicable. Instead look at the Grace of Allah that is with them. Look at the splendour of the one who arrives through the ship and do not look at the heights of the mountains of Reason.
The power of Allah is such that with one wave, He can turn the ship upside down. But the ship which travels in the shadow of Allah's Mercy, in spite of its outward weakness and the evil intention of Shaytaan, it will pass through all the trials in safety. If one is not going to follow this advise, then in the end one will have to admit the shortcomings of the intellect.Hence, if a person needs to find safety from faults and sins, he will have to become closely connected in love with the saints of Allah. Then he will not suffer losses. People who wish to travel on the path of deen with only reason are breakers of their 'tobah'.
When Shaytaan gives one blow in their direction, their 'tobah' is broken down. Yet their arrogance is such that they look down upon the saints of Allah. Such people remain imperfect throughout their lives. So, 0 People! Seek for yourself a way towards Allah and consider the company of the saints as medicine.
