The science of medicine is not to blame for the existence of such a state of things; but it is one of the attributes of human animal nature, and we leave it to the intelligent observer to judge whether this nature has changed a great deal since the time of Paracelsus, or whether there is still an army of quacks, legalized or illegal, who have written the motto “_Mundus vult decipi, ergo decipiatur_” upon their flag. Official science has undoubtedly progressed during this century, but merely intellectual acquisitions do not necessarily make a man wiser; the greatest scoundrels have been men of great intellectuality without spirituality. Wisdom consists in the self-recognition of truth, and there are many who are “ever learning and never able to come to the knowledge of truth.”[53] This spiritual knowledge does not belong to the faculties of men’s lower intellectual nature, but to his higher nature alone; and it is therefore of paramount importance that the development of that higher nature should receive more attention than it is receiving at present. A mere improvement in morals or ethics is quite insufficient for that purpose. Morality is the outcome of reasoning; Spirituality is the superior power due to the manifestation of self-consciousness on a higher plane of existence, the illumination of the mind and body of man by the power and light of the spirit filling the soul. When spirituality becomes substantiality in man, then only will his knowledge be of a substantial kind. This spiritual substantiality, or, in other words, the realization of the highest ideal, is the work of the gradual evolution of mankind; which, as has been said by the ancient alchemists, “may require for its accomplishment thousands of ages; but which can also be accomplished in a moment of time.” It is not a product of man’s labour, but of the descent of the light of divine truth, the “grace of God” which will come to everyone whenever he is ready to receive it. It is therefore not dependent on anyone’s willing or running,[54] but on the action of the spirit of the true divine Self, which is ever striving to become manifest in man. This interior development is not the consequence of the acquisition of any new theories in regard to the nature of the constitution of man; but takes place through the overcoming of the lower elements in his nature, by means of which his higher nature can become manifest. But in order to induce and enable him to employ his powers intelligently for the purpose of conquering his lower nature, he should learn to know theoretically his own constitution and the nature of the higher powers in him.
