The fourth sort of supplication is the most well-known; it is our supplication. This too is of two sorts: one is active and by disposition, and the other, verbal and with the heart. For example, having recourse to causes is an active prayer. To gather together causes is not in order to create the effect, but through the tongue of disposition to take up an acceptable position in order to seek the effect from Almighty God. To plough a field is to knock at the door of the treasury of mercy. Since this sort of active supplication is directed towards the Absolutely Generous One's Name and title, it is accepted in the great majority of cases.
The second sort is to offer supplication with the tongue and the heart. It is to seek certain wishes which the hand cannot reach. The most important aspect, the most beautiful aim, the sweetest fruit of this is this: "The one who offers the supplications knows that there is Someone Who hears the wishes of his heart, Whose hand can reach all things. Who can bring about each of his desires, Who takes pity on his impotence, and answers his poverty."
O impotent, needy man! Do not neglect a means like supplication, which is the key to the treasury of mercy and to an inexhaustible strength. Cling to it! Rise to the highest peaks of humanity! Include in your supplications those of all the universe, like a king! Say, From You alone do we seek help8 like a servant and deputy representing all the universe! Be on the Most Excellent Pattern of creation!
