"Now, occultism is not like mystic faculty, and it very seldom works in harmony either with business aptitude in the things of ordinary life or with a knowledge of the canons of evidence in its own sphere"

This quote by Arthur E. Waite is referring to the practice of occultism, which is the belief in supernatural forces and phenomena. Waite is suggesting that occultism is not the like mysticism, and it is not compatible with the useful abilities and understanding required to be successful in everyday life. He is also implying that occultism does not abide by the very same requirements of evidence as other fields of study. Simply put, occultism is not a trusted source of knowledge and should not be taken as truth. Waite is warning against relying too greatly on occultism, as it is not a reputable source of knowledge and can result in misdirected beliefs. He is recommending that it is better to count on more practical abilities and knowledge in order to succeed in life.
