I believe it was Paracelsus who said that, in order to develop spiritually, man must spend at least half an hour every day in seclusion, in silence, and without thinking about anything. In other words, man must cultivate the habit of meditation. It is curious that the recommendation comes from a Westerner who lived in a time when there were no good translations of Eastern texts. Therefore, it is to be assumed that Paracelsus came to such conclusions through experience, the same experience that is indispensable to validate what has been taught for so many centuries in the East. There is no denying it: meditation, if practiced regularly, proves to be undoubtedly beneficial. With time, it is possible to notice ostensible differences between the days when one meditates and the days when the practice is postponed. The exercise of establishing one’s own will over the mind, i.e., the exercise of silencing, annulling, and controlling it, greatly strengthens not only self-control, but also the ability to choose. Not to mention the sensations that come from the mental state induced by deep meditation, and the doors that are opened by continuous effort. In short, the wise alchemist knew what he was talking about and was, without a doubt, a superior man.
