To every act that you exhibit; either good or bad is preceded by a mental agreement from within the mind. Things don't just happen just by themselves. Someone or something makes them happen. The human mind can be liken to a piece of land, it will always produce whether we cultivate it or not. All by itself, if left uncultivated, will produce weeds and every other unwanted seeds. In another way round, if patiently we have dedicated ourselve to cultivating it we then can be assured of yielding good produce when the seasons are due for harvest. Your mind is your most valuable asset which you must guard and protect with all deligence.
