Moderation
One of the essentials in the making of a man engaged in spiritual pursuit is moderation. It is a very wide term and covers every phase of human activity. It means balance in all senses and faculties, nothing more or less than what is naturally required at the time for any specific purpose, without its slightest impression on the mind.
