It's raining and you need to hold an umbrella. If there is no umbrella, he doesn't have to hold one, or he can get one himself.
He can do all these things alone. If the sense of security is to have an umbrella when it rains, then he does not need this umbrella.
Or to put it another way, he never owned the umbrella.
Or maybe, in a confusing series of strange events, he had unknowingly possessed the umbrella.
What you are and what others are are all reflected in your heart. Whatever you think is is what you think it is.
But you can't let others agree with what you think.
Purpose: Human beings are not the masters of all things
