Acervulus Cerebri: Theosophy Dictionary on Acervulus Cerebri

Acervulus Cerebri:

Acervulus Cerebri Brain-sand; minute particles of a yellowish, semi-transparent, hard, brilliant substance found in the pineal gland in the human brain. Its exceptional absence occurs in congenital idiots, in young children, and in the senile aged. The physiologists report that this "sand" is composed of alkaline phosphates and carbonates and some animal matter, but they fail to account for its presence or purpose.

The fact that this brain-sand is of mineral rather than of osseous character is in keeping with the occult history of the once external, active third eye of early humanity. The ancients knew that, with the racial evolutionary descent into gross matter, this spiritual eye, gradually becoming atrophied and petrified, retreated deeply within the developing brain when its course was run (SD 2:294&n). The pineal gland being the chief organ of spirituality in the human brain at present, this mysterious sand is the result of the work of mental electricity upon the surrounding matter. This is based on the ancient idea that every atom of matter is only a concretion of crystallized spirit or akasa, the universal soul.

"The Encyclopedic Theosophical Glossary is presented to the public as a work in progress. The manuscript, produced originally in the 1930s and '40s, is currently being revised and expanded by the Editorial Committee. Theosophical University Press is presenting this working version online because, even in its present unfinished form, we feel that the contents will be of value to students of theosophical literature, particularly of the works of H. P. Blavatsky. "
