 It is the seeing into the true nature of existence, the seeing that "all objects are without self-substance".The full phrase is "fushō fumetsu", "unborn and undying", or "no creation and no annihilation", but in later years Bankei only used the term "unborn", since Bankei thought it logically impossible to say that something which has not been created is being destroyed, rendering the term "undying" redundant.However, it is not logically impossible for something which has always existed to cease existing, hence the utility of employing both terms.
