There is still the problem of food; as long as our body is compelled to take in foreign matter in order to subsist, it will absorb at the same time a considerable amount of inert and unconscious forces or those having a rather undesirable consciousness, and this alchemy must take place inside the body. We were speaking of the kinds of consciousness absorbed with food, but there is also the inconscience that is absorbed with food quite a deal of it. And that is why in many yogas there was the advice to offer to the Divine what one was going to eat before eating it {Mother makes a gesture of offering, hands joined, palms open}. It consists in calling the Divine down into the food before eating it. One offers it to Him – that is, one puts it in contact with the Divine, so that it may be under the Divine influence when one eats it. It is very useful, it is very good. If one knows how to do it, it is very useful, it considerably reduces the work of inner transformation, which has to be done.
