Answer: The science of the Sufis teaches that in the mind and in the body a blockage is produced by the lack of development of the sympathetic nature. In the physical body are some nervous centers which are awakened by sympathetic development and by lack of sympathy they are closed. It is therefore that a butcher is less intuitive: everything that keeps man away from sympathy robs him of intuition, because sympathy develops a life in the finer centers, the nervous centers, and the absence of sympathy takes away that life.
