"In general, bear in mind that narcotics are not advisable for the followers of Agni Yoga. Also, smoking is harmful, as well as the immoderate use of alcohol. Even meat is harmful, as it fills the organism with decayed particles. Of course, as a physician, you realize how carefully one should change one’s habits so that there will not be any harmful reactions. But are there many people who could do it gradually? However, Agni Yoga is inaccessible for smokers and drinkers. (28 August 1931)1"
