Yongye ice field is worthy of its name. For most of the year, the sky is covered by frozen clouds, like an endless dark night.


    But occasionally, when the clouds disperse and the light comes out, it has the most brilliant sunshine in the whole ancient holy world, like a rainbow of seven colors.


    On the last day before Li Yao left the ancient holy world, he saw such beautiful sunshine.


    It''s like a rainbow waterfall spilling over the whole ice sheet, and countless colorful bubbles are pounded out from the ground, surging between heaven and earth.


    With such a magnificent and soul stirring iridescent light as the curtain, Li Yao saw master kuchan sitting on the bow of a star ship, holding a micro crystal brain, reading the classics wholeheartedly. It was so quiet and solemn that it was like ten thousand lotus flowers blooming around the monk.


    Li Yao was a little upset, so he came out and walked casually. This made him move. He could not help flying to the back of the star ship moored on the ice and crept to master kuchan.


    The cultivation reached the height of Li Yao, and his eyesight was far beyond people''s reach. Before he came to the monk''s back, he saw clearly the classics that the master was studying, which were——


    "A hundred stories of youth and Zen master", "a collection of Chicken Soup for the soul", "parchment: ancient wisdom from the world of tree and sea", "women are born elegant"


    Li Yao: "cough, cough, cough."


    Master kuchan: "since Li Daoyou is here, why don''t you stop? Monk, listening to your heavy and chaotic steps, is it like you are worried?"


    "Nothing."


    Li Yaodao said, "I want to thank you for your Dharma protection on that day. Without the help of the master and other Taoist friends, maybe I would have been possessed and doomed!


    "In addition, worry is a little trouble. I wanted to discuss with master originally, but... Master is so busy studying Classics, forget it."


    "These classics from the Xingyao Federation are really mysterious. Many of the reasons make the monk open up and gain a lot."


    Master kuchan sighed and said, "if Li Daoyou doesn''t dislike the monk''s clumsy tongue, you might as well tell me your troubles. The monk just tries to explain it with the Zen principles and Buddhism in the chicken soup of the soul. Don''t worry, it''s a monk''s practice and there''s no charge."


    "... all right."


    Li Yao stepped forward and sat cross legged opposite master kuchan. Looking at the colorful and unfathomable sky, he pondered, "has master ever thought that everything in front of him is illusory, that there is a world beyond the world, and that there is a problem of the universe above it? If there is a universe above the universe, and our universe is just a projection of the higher universe, or even just an illusory game, how can we determine whether we are "real" or "illusory", and what is the significance of what we do? "


    Master kuchan smiles and says, "eat and sleep."


    Li Yao frowned: "master, I really want to ask you for advice. Don''t you use such an old joke to treat me?"


    This "eat, sleep" is a small story. It says that a young man asked Zen master what "trouble" means. Zen master said "eat, sleep" with a smile. Young man asked what "practice" means. Zen master said "eat, sleep" with a smile. Young man was puzzled, but Zen Master explained, "trouble is sleeping when it''s time to eat and thinking about eating when it''s time to sleep; The so-called practice is to eat when it''s time to eat and sleep when it''s time to sleep.


    This is a rather old spiritual story. It stinks in the streets of the Xingyao Federation. With Li Yao''s extensive knowledge and strong memory, it''s naturally clear.


    But master kuchan coughed, cleared his throat and said: "although the case is old, the truth is new - what is" true "and" illusory ", which is the most difficult and unnecessary thing in the world.


    "In the Xingyao Federation, there is even a story of" brain in a VAT "- today, when the cultivation of magical powers and virtual magic weapons are so developed, it has been able to create a vivid, almost 100% virtual illusion. Even if someone has only one brain, he is put into a vat full of nutrient solution, and thousands of crystal lines are connected to his brain, Can make him mistakenly think that he is full of limbs, living in the real world.


    "So, how can this person tell whether he is living in the real world or a brain in a vat, living in an artificial fantasy?


    "And how can we tell that the so-called" three thousand worlds "is the ultimate reality. There is no higher level existence in our world, which creates and designs everything. Our whole world is a huge" brain in a VAT "


    Li Yao nodded: "yes, that''s the problem. How can we distinguish and prove it?"


    "It''s impossible to tell, and there''s no need to prove."


    Master kuchan said, "of course, you can doubt that the three thousand worlds we live in and the endless three-dimensional universe are all higher-level existence. Er, for example, a brain in a vat created by a certain" four-dimensional life "in the laboratory is just a small projection of the four-dimensional world, which is just an experimental subject of this" four-dimensional life ".


    "However, even if this four-dimensional life really exists, it is a Legendary God and devil. Is the four-dimensional world in which it lives the so-called" reality "? Can this four-dimensional world, which we can''t understand, also be a projection of a five dimensional world, a painting drawn by a painter in the five dimensional world?


    "And the five dimensional painters in this five dimensional world are the ultimate reality? Will the whole five dimensional world, in the final analysis, be a long poem sung by a frustrated poet in the six dimensional world? And this six dimensional world is a crystal clear dew on a small petal of the seven dimensional world? And the seven dimensional world is a strange creature in the eight dimensional world. It''s a dream when it''s dozing


    Li Yaomu gaped: "this, is this possible?"


    "If you think brain in a vat is possible, then four-dimensional lab, five dimensional pictures, six dimensional poetry, seven dimensional dew and eight dimensional monster''s dream are all possible."


    Master kuchan said, "even if their probability is very small, no matter how small the probability is, it is doomed to happen in the eternal time, space and infinite dimensions.


    "This is the truth of what futuzong said:" one sand, one world, one tree, one Bodhi ". In the concept of transcending time, space and dimension, a dust is the same as the three thousand worlds. No one is more" real "or" illusory "than anyone else.


    "The world doesn''t matter whether it''s true or not. It''s your heart and the way you look at the world that can tell the true from the false. If you have the mentality of" eating when you eat and sleeping when you sleep ", then every world is true; If you are eating, but you want to sleep, and you are in our three-dimensional universe, but you are confused and uncertain, and you are entangled in the so-called "truth" to ponder over the four-dimensional world, what if you reach a higher level one day? After arriving at the four-dimensional world, you will doubt whether everything in front of you is a picture of the five dimensional world; After you reach the five dimensional world, you will worry about the existence of the six dimensional poets... Where can you find the final truth when you are broken one by one and never satisfied? "


    Li Yao was stunned for a long time. He touched his nose and said with a bitter smile: "when I was a child, I was full of confusion about the world. I had 10000 questions in my mind. I thought that as long as I practiced hard and became the most powerful cultivator in the world, I could find the answer.


    "Who knows, the strength is stronger and stronger, and the realm is higher and higher. In the past ten thousand questions, we have found answers, but there are 100000 new questions, one million new questions, and we are more and more confused!"


    "It''s nature, like a little bubble."


    Master kuchan spread out his palm, and a trembling flash bubble appeared in the palm. With his power injection, the bubble became bigger and bigger. "Li Daoyou, you see, the bubble is bigger and bigger, and it is filled with more and more" answers ", but the" surface area "of its contact with the outside world is also bigger and bigger, so it can feel more" unknown "and" confused ". Every big bubble has a point, As soon as a puzzle was uncovered, ten new puzzles came into contact. How can it be so big that it can engulf the whole planet and universe? Therefore, the "unknown", "confusion" and "trouble" are endless


    Master kuchan''s palm trembled slightly, and the air bubbles swayed and flew into the sky. Under the sunshine, they bloomed with brilliant colors.


    The monk narrowed his eyes, looked at it intently, and murmured: "even so, although the confusion is more and more, there is no end to it, but we should continue to practice, because... You see, how beautiful the bubble is!"


    Together with master kuchan, Li Yao silently watched the bubbles fly higher and higher, and gradually fly to the colorful clouds. After thinking for a long time, he said: "master, I think what you said is very profound, mysterious and reasonable. But when I think about it carefully, I feel like you didn''t say anything."


    "Nonsense."


    Master kuchan said, "you amuse the monk with an unanswered question like" brain in a VAT ". Instead of swearing at you and kicking you off the starship, the monk is willing to give you a perfunctory answer. He has done his utmost. What can I do?"


    Li Yao was not annoyed, and said: "well, master, in your opinion, the higher the bubble flies, where will it fly?"


    "How do I know?"


    Master kuchan looked at the bubbles that had melted into the clouds, perhaps through the clouds and flew to the endless starry sky, and a layer of golden light appeared on his face. He said faintly, "this question is about to ask Daoyou li himself. After all, I am neither a Buddha nor a Bodhisattva, but just a... Ordinary bald head."
