Vegetarianism and its occult meanings [EPUB ebook] 

How does occultism regard vegetarianism ? It regards it very favourably, and that for many reasons. These reasons may be divided into two classes – those which are ordinary and physical, and those which are occult or hidden. There are many reasons in favour of vegetarianism which are down here on the physical plane and patent to the eyes of any one who will take the trouble to examine the subject; and these will operate with the occult student even more strongly than with the ordinary man. In addition to these and altogether beyond them, the occult student knows of other reasons which come from the study of those hidden laws which are as yet so little understood by the majority of mankind.
