Is the third original genius of the Jupiter sphere, who has under his command all knowledge of the whole cosmic hierarchy. He is the supervisor of the mind, of the intellect, i. e. of all theoretical knowledge in all fields of science. Ambriel directs the maturity for knowledge, the capacity of perception of each being in the whole cosmic hierarchy. Taking into consideration the grade of maturity and development, this genius not only directs the intellectual power of perception and the intellectual faculties of the individual, but of the total of the inhabitants of all planets. Under his range of competence come all the sciences and arts on all planets which have to do with the mind and intellect. The magician who has got into contact with this genius will be made acquainted, depending on the grade of his development, with a kind of knowledge which truly is only ac- cessible to such initiates that have learned to work consciously with the Jupiter sphere by force of the Akasha-principle.
