Mind is dual, it always divides things into polar opposites: the conqueror and the conquered, the observer and the observed, the object and the subject, the day and the night. It goes on dividing things which are not divided. Neither is the day divided from the night, nor is birth divided from death. They are one energy. But mind goes on dividing everything into polarities, opposites. Nothing is opposite in existence; every contradiction is only apparent. Deep down all contradictions are meeting together.
