He who is filled with the knowledge of names and forms has no capacity for the knowledge of God.

A man filled with earthly knowledge and what he calls learning is often only the knowledge of names and forms has no capacity for the knowledge of truth or God. It is the innocent and pure soul who has a capacity for learning. When a person comes to take a lesson on any subject, and he brings his own knowledge with him, the teacher has little to teach him, for the doors of his heart are not open. His heart that should be empty in order to receive knowledge is occupied by the knowledge that he already had acquired.

Intellect is the knowledge of names and forms, their character and nature, gathered from the external world. It shows in an infant from birth, when he begins to be curious about all he sees; then, by storing in his mind the various forms and figures he sees he recognizes them as an addition to his knowledge of variety. Man thus gathers the knowledge of numberless forms of the whole world in his mind and holds them... and calls that 'learning'. This becomes his world, although it neither gives him a sense of unchanging comfort, nor does he thereby gain an everlasting peace.

Wisdom is contrary to the above-named knowledge. It is the knowledge which is illumined by the light within; it comes with the maturity of the soul, and opens up the sight to the similarity of all things and beings, as well as the unity in names and forms. The wise man penetrates the spirit of all things; he sees the human in the male and female, and the racial origin which unites nations. He sees the human in all people and the divine immanence in all things in the universe, until the vision of the whole being becomes to him the vision of the One Alone, the most beautiful and beloved God.

Although the tongue of God is continually speaking through all things, yet in order to speak to the deaf ears of many among us, it is necessary for Him to speak through the lips of man. He has done this all through the history of man, every great teacher of the past having been this guiding spirit living the life of God in human guise. In other words, their human guise has been various coats worn by the same being, who only appeared to be different in each. Shiva, Buddha, Rama, Krishna on the one side; Abraham, Moses, Jesus, Muhammad on the other ... Those who knew the messenger when they saw him, recognized him in whatever form or guise; those who could only see the coat went astray. To the Sufi, therefore, there is only one teacher, whatever name he may be given at different periods in history; and he comes constantly to awaken humanity from the slumber of this life of illusion and to guide man onward towards divine protection. As the Sufi progresses in this view he recognizes his Master not only in the holy ones, but in the wise and in the foolish, in the saint and in the sinner.
