Nature herself provides him with a fruitful field of research, and his own garden will be a most suitable laboratory and study. He may endeavour to pierce the physical veil that hides from normal physical sight the flowing forces of magnetism, electricity, sound, heat, light and vitality which animate the vegetable kingdom. He should obtain the help of those with scientific training and attainments if possible, for they are accustomed to the methods of scientific research by which alone his observations may be checked, and accuracy and reliability achieved. As his powers unfold, he may widen the range of his studies to include the hidden side of atomic, chemical and electrical phenomena, the super-physical counterparts of objects, such as the subtle bodies of plants, animals and men, the elemental kingdom of Nature, nature-spirits and angels. The super-physical realms of existence and the discarnate entities who inhabit them may then be studied, and attempts be made to develop and use the faculty of clairvoyance in time and space. “Investigations such as these have been continuously carried out by an unbroken succession of students for millions of years. The results of their efforts form a vast store of knowledge which is called the Ancient Wisdom, and is now being made, available gradually through the publications of the Theosophical Society The student will, therefore, be able to check his own findings by those of his predecessors in occult research, and, in his turn, to add to their discoveries, thereby enriching the sum total of human knowledge.43 It must be understood clearly, however, that clairvoyant research is by no means the only, or even the most important, method of acquiring knowledge; neither is the development of this power a necessity for either spiritual progress or the study of occultism. A surer method exists, and a far more valuable faculty is available to man. This faculty is spiritual intuition. By its means knowledge may be gained upon any subject whatever without the laborious process of developing and using clairvoyant powers. Though the two faculties may be usefully employed as complementary methods, the intuitive is far more important and valuable than the psychic. Unless, therefore, the student can fulfil the, qualifications and conditions stated above, he will be better advised to devote the whole of his energies to the development of his intuitive faculties.
