Fate has a script.
Perhaps for the unknowable living beings, it has no interest in interfering, but for certain Sons of Destiny (Lu Ping'an: fate's puppet), it will "arrange" things for them.
It doesn't need to arrange what you say or what you do, but at a specific time, it will place you where you're supposed to be, confront you with the difficulties and environment you need to face, make you meet the people you should see, and everything will naturally happen.
What you say and think is not important... ultimately, you'll do what fate needs you to do.
You will dance and sing on the stage of fate and then take a bow after you've completed your mission.
Why? How can it be done? You are nurtured by the world; your consciousness, your thoughts, your limits are always within the calculations of fate.
"How can one who has not seen the universe imagine the true nature of the world beneath their feet? Your vision determines the boundaries of your choices..."
