The suggestions that create illness or unhealthy conditions of the physical being come usually through the subconscient—for a great part of the physical being, the most material part, is subconscient, i.e. to say, it has an obscure consciousness of its own but so obscure and shut up in itself that the mind does not know its movements or what is going on there. But all the same it is a consciousness and can receive suggestions from Forces outside, just as the mind and vital do. If it were not so, there would not be any possibility of opening it to the Force and the Force curing it; for without this consciousness in it it would not be able to respond. In Europe and America there are many people now who recognise this fact and treat their illnesses by making conscious mental suggestions to the body which counteract the obscure secret suggestions of illness in the subconscient. There was a famous Doctor in France who cured thousands of people by making them persistently put such counter-suggestions upon the body. That proves that illness has not a purely material cause, but is due to a disturbance of the secret consciousness in the body.
To bear quietly and in silence does help to release from the reaction of grief, if one makes the vital quiet; but it should be at the same time surrendered to the Mother. For the Mother to know from within is not enough; there must be this laying before her and giving up to her so that the reaction may disappear.
