Description of The Mind over Matter
Generally said if the affected person should free himself from materialism or minor important things, thus set his mind over those and hence care about more crucial things, not seldom his own well-being for his plans on particular upcoming events might seriously damage his health, his reputation or the like, thus could cause him more harm than intended before - therefore mind over matter settles the issue in advance by barring the person from dealing with the issue(s) himself.
This proverb also perfectly goes with the generic Buddhist and his lifestyle for he strives for a life without profane belongings or devaluing materialism. Typically, money, power or tangible richness can change one's character to the bad and in order to prevent the person from becoming alike he should always keep mind over matter in his mind.
Are we ready to do this or are we slaves of our own desire to belong to this corrupted society?
