Concerning participation in spiritual work
If you have a serious physical or psychological condition, you are advised against taking part in activities that call upon spiritual energies without prior consultation with an experienced meditation teacher. Where serious illness or imbalance is present, it is recommended that the body and mind focus on healing and regaining balance. In these cases, it is better to work on healing in cooperation with health care practitioners through, for example, relaxation, positive thinking and stress reduction. Also, if you use or have used illegal drugs, psychoactive medications (for example, antidepressants, mood stabilisers, tranquillisers, hypnotics and so forth), or alcohol (more than the occasional social drink), a minimum of 3-7 years free of using such substances is recommended before it is advisable to participate in spiritual work.
