So far we have considered the neural and psychonic theories. We shall now discuss the endocrine theory of chakras. There is no theory called as such but the identification in some circles of the chakras with certain glands lends the view that they have a plausible theory of glandular correlation. The theory is stated in two sentences. It is said the pineal gland and the pituitary glands correspond with the Sahasrara. Des Cartes * and his followers held that the pineal gland was the seat of the soul. The interest lies not in the fact that the theory has the remotest chance of being accepted but as revealing how a little known organ has been pitched upon as the centre of the soul, or the Sahasrara, the pineal gland and the centre of the Divine.
The endocrine glands of the body are closely connected with the metabolic processes of the body and their importance is very great. With the exception of the reproductive organs, the ductless glands are all characteristic of the vertebrate group alone and some authorities regard them as relatively recent acquisitions and their activities as something which came into existence after the development of the central and sympathetic nervous system. But it would seem that the appearance of the primitive nervous system and the reproductive organs are about the same time and the development of the nervous system into the autonomic system and the cranial series occurs before the appearance of the endocrine system.
The number of these glands is seven if we add the thymus and the pancreas, namely, the pineal, the pituitary, the thyroid, the thymus, the pancreas, the adrenal and the genital. This correspondence with the seven plexuses is no doubt a basis of this hypothesis. The location of the pineal in the cavity of the head, with the pituitary close to it point to the value of the theory of glands; added to this we have the version of a Upanishad which speaks of the genital organ as the Svadhisthana.
Dr. Sajous in his valuable work on 'Internal Secretions and the Principles of Medicine' says that there is complete coordination between the several glands. "the close linkage of the several glands to each other confirms the view that they form a single system in close touch with each other and the blood circulation and the nerves of the central system. The pituitary is
