The trees give forth fruit, lose their leaves and go dormant.
Flowers bloom in praiase of all creation, wither and die.
But the Spring comes, trees put forth leaves again, and all the seeds germinate. It is the same species but not the same flower or fruit of the tree. Or look at school. Say you are in the third grade and a group of fellow students set themselves up as the only ones from that grade to trutly understand the words of the teacher. What if they were to tell you there is nothing beyond third grade, that everything will come to an end with the final exam.
