[Footnote 44: The cause of a certain disease may exist not only in one of these five classes, but in more. For instance, a hæmorrhage of the womb may be caused by mental excitement in connection with a state of weakness of resistance in the tissues of the organs; insanity may be caused by mental, moral or physical circumstances; blindness may be the result of physical causes or of mental excitement; a bodily defect the result of antenatal _Karma_, or of physical causes. In the clockwork of nature all the wheels are connected by one common chain. Therefore not only one of these causes but all of them ought to be known and taken into consideration; but each of the corresponding five methods of treatment contains in itself all the elements for effecting a cure. It is therefore not necessary that a physician should practise all the five methods of treatment; but he should have a thorough knowledge of the method which he has chosen, and be well versed in it and stick to his method; but he should not believe his own method to be the only true one, and reject others of which he knows nothing.] [Footnote 45: The soothing power of blue, the exciting effects of red, the invigorating effects of yellow, etc., deserve a great deal more attention than they receive at present. The reason why the “blue light cure” has caused only a passing excitement, is because it was indiscriminately used and its laws not understood.] [Footnote 46: “Paracelsus,” p. 141.] [Footnote 47: Professor O. Korschelt in Leipzig invented an instrument for that purpose.] [Footnote 48: See “Paracelsus,” p. 138.] [Footnote 49: All forces may become manifest in a threefold form. There are universal, animal and spiritual “magnets”; a physical electricity, an electricity of life, a spiritual electricity, etc., etc.] [Footnote 50: _Dr Babbitt’s_ “Principles of Light and Colour.”] [Footnote 51: F.
