Note: CMI’s Virtual Library is unable to carry out a thorough evaluation of the hundreds of thousands of pages available to access. For this reason, we rely on the collaboration of users to communicate any work and the respective page on which they believe they have found inappropriate content, such as a description of modes of recognition or excerpts from a ritual, through the informed email. Under no circumstances will CMI and/or its directors be responsible for the misuse of the contents of this Library or for acts performed by a user, based on information obtained from it. The contents of the works are the sole responsibility of their authors.
