"It is forbidden to dwell in the vicinity of any of those with an evil tongue, and all the more to sit with them and listen to their words."
Moses ben Maimon, commonly known as Maimonides and also referred to by the Hebrew acronym Rambam, was a Sephardic Jewish rabbi who is widely acknowledged as one of the most prolific and influential Torah scholars of the Middle Ages. Originally from Córdoba, where he was born on Passover Eve of 1135 or 1138, his family was exiled from Muslim-ruled Spain when they refused to convert to Islam shortly
"Having concluded these introductory remarks I proceed to examine those expressions, to the true meaning of which, as apparent from the context, it is necessary to direct your attention. This book will then be a key admitting to places the gates of which would otherwise be closed. When the gates are opened and men enter, their souls will enjoy repose, their eyes will be gratified, and even their bodies, after all toil and labour, will be refreshed."
Maimonides"He will punish all the evil deeds of men, although they have not been prohibited by a prophet, if common sense warns against them, as e.g., injustice and violence. ...it is distinctly added that he who does a good thing without being commanded, receives nevertheless his reward. The same principle is expressed in all the sayings of our Sages."
Maimonides"This must be our belief when we have a correct knowledge of our own self, and comprehend the true nature of everything; we must be content, and not trouble our mind with seeking a certain final cause for things that have none, or have no other final cause but their own existence, which depends on the Will of God, or, if you prefer, on the Divine Wisdom."
Maimonides"There is one [disease] which is widespread, and from which men rarely escape. This disease varies in degree in different men … I refer to this: that every person thinks his mind … more clever and more learned than it is … I have found that this disease has attacked many an intelligent person … They … express themselves [not only] upon the science with which they are familiar, but upon other sciences about which they know nothing … If met with applause … so does the disease itself become aggravated."
Maimonides"After having explained this division, I contend that no intelligent person can assume that any of the actions of God can be vain, purposeless, or unimportant. According to our view and the view of all that follow the Law of Moses, all actions of God are "exceedingly good."
Maimonides"The third class of evils comprise those which everyone causes to himself by his own action. This is the largest class, and is far more numerous than the second class. It is especially of these evils that all men complain,—only few men are found that do not sin against themselves by this kind of evil. ...This class of evil originates in mans vices, such as excessive desire for eating, drinking, and love; indulgence in these things in undue measure, or in improper manner, or partaking of bad food. This course brings diseases and afflictions upon the body and soul alike."
