If. Everyone in the world is willing to use what-ifs, hoping to go back to the past, change the things they regret and missed, and look forward to a happy ending.
But the human heart is a desire, and the most difficult thing to satisfy is the human heart, and perfection itself is also a kind of incompleteness. It is incomplete because it has not experienced incompleteness. This is an unsolvable paradox, at least it seems that it still has no solution. Therefore, there are very few people in the world who can achieve Consummation, and those who can probably become dead. When a person dies, his will also dies. From this, we can see that it makes sense for Buddhism to call the end of life Nirvana.
But no one in the world has ever been able to find a way to realize "what if". Time always moves forward slowly and unhurriedly, unstoppable and unstoppable. There are kings who seek immortality, but I have never heard of anyone seeking a way to turn back time. Because time is like the rising and setting of the sun and cannot be controlled by humans. The time flies by in a blink of an eye, and life is always endless because of this.
Some things just haven't been discovered, but that doesn't mean they don't exist. For example, a life without a soul thousands of years later, a secret technique called souling, a tunnel called time...
Time goes by and time is hard to come by. In the passing time, can we still find the past that has passed away...
