When the awakening of kundalini takes place it is important to have the correct diet, as food influences the mind and your nature. At the time of awakening, certain physiological changes occur in the body, particularly in the digestive system, and the digestive process is frequently disturbed, or hunger vanishes completely. Therefore, a kundalini aspirant has to be very careful about his diet.
Scientific observations have shown that the awakening of kundalini is generally accompanied by a state of nervous depression. The inner body temperature undergoes erratic changes and drops so much that it becomes much lower than the outer body temperature. Metabolism slows down and sometimes it even stops completely. Consumption of oxygen also falls. Therefore, when you are experiencing kundalini awakening your diet must be very light and easy to assimilate.
The best diet for a kundalini yogi is boiled food. Crushed wheat, barley, lentils and dal are excellent foods, particularly when they are in a liquid form. Fats and greasy foods should be avoided and protein should be kept to a minimum. This will take any strain off the liver, because when the mind undergoes a crisis, the liver is overtaxed.
It is good to increase the carbohydrates in your diet, eg. rice, wheat, maize, barley, potato, etc., because carbohydrates help to maintain the inner body temperature and they do not require much heat to digest. Eggs, chicken and other heavy foods do not produce much heat themselves, but they require heat for digestion.
The yogic diet is macrobiotic, it is simple, plain and relatively bland. From time to time, fruits and roots can also be taken, but they are not essential.
There are certain foods which are not meant for the human body at all. If you analyze your digestive and salivary secretions and the durability of the mucus membranes in the alimentary canal, you will find that they are not really meant for digesting meat and uncooked foods.
The food we eat is not merely to satisfy our taste. Every food item has an essence in it, and in yoga we call this sattva. Sattva means the ultimate essence of food, but please do not mistake this for vitamins or minerals. Sattva is the more subtle form of food. When you eat for the sake of taste or enjoyment, instead of attaining the sattva you only get the gross things. That is why the yogis and saints of all traditions have always lived on the minimum possible food during periods of sadhana.
When we overeat we create a burden for the digestive system, and when the digestive system is overburdened we are unable to extract the sattva from the food. Sattva is a substance which nourishes the thoughts and nervous system. When the thoughts are fed with sattva they are more refined and pure, and one is able to live in higher consciousness. Therefore, it is beneficial for a sadhaka to fast from time to time. When the body is kept light and pure it is far more capable of extracting the sattva from food.
In the diet for kundalini aspirants, condiments have a very important role to play. Condiments such as coriander, cumin seeds, tumeric, aniseed, black pepper, green pepper, cayenne, cloves, mustard seed, cardamom, cinnamon and so on are also called digestives as they aid digestion. These substances are not spices for taste; they are condiments which have the same properties as the enzymes in the body, and by helping to break down the food for digestion, they conserve vital energy and help to maintain the body's internal temperature.
Instead of cooking the food in your stomach, it is best to cook it properly in the pan. Five or six condiments should be added during cooking to liberate the enzymes and chemicals which enhance digestion. The combination of heat, condiments and enzymes breaks down the food into smaller and more basic components, thus making it easier to digest.
