King Flower shows what is noble.
King Flower, the Master, is describing what is noble. Here he is revealing the Noble Eightfold Path of Buddhism. Apriori does not fully understand all of this. Apriori is however fully engaged in practice. Understanding cause and effect Apriori realizes that to be the king is to be mindful of practice.
Apriori is also starting to understand that he is a reflection of King Flower or even that King Flower is a reflection of him. Apriori wants to be the King Flower and the King Flower shows that meditative practice is the way to being the master of everything.
