Yoga also considers alcohol to have an adverse effect on the central nervous system, and in particular the brain. The integrity of the central nervous system is considered very important by the yogis, since one of the goals of yoga is to improve the health of this system, and much of the progress of yoga is achieved via this vital communication system. Modern science agrees with yoga on this point, since alcohol is known to first stimulate and then shortly afterwards depress the central nervous system. Alcohol also causes poor sleep. Alcohol cannot compare with the effects of yoga.
Yoga produces a natural stimulation without the depressing after-effect.
Yoga also produces a general feeling of elation. The increase in life force produced by practicing yoga cannot be duplicated by drugs. The yogis place great emphasis on eating slowly. It is more important than on the type of food eaten. They claim that even nutritious food is not properly digested if eaten quickly.
