' Wisdom '...

The man filled with the knowledge of names and forms has no capacity for the knowledge of Truth.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

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.
