It is not surprising if a material person becomes ill, nor is it amazing if a spiritual person is unwell. The former becomes ill because he has lost his rhythm, the latter is ill because he could not keep to a rhythm which is not his own. Be one spiritual or material, since one has to live in the midst of the world, one shares the conditions of all those who are far and near, and one subjects oneself to the influences, desirable or undesirable, coming from all around. One cannot close one's eyes, nor can one close one's heart, to the impressions which continually fall upon one. The best one can do is to keep a careful watch against all that comes upon one causing irregularity, inharmony and disorder, to be resigned to all one has to pass through, and to be courageous in order to overcome all that keeps one back from health and perfection.
