Someone he doesn’t know secretly wanted to help this man. So when his hands are free, he bends down and frees the chain from his feet and then he begins to wonder how to go up there.
This is so because he doesn’t even know if he can go up since he’s been accustomed to walking only straightforward, not down, not up. So, he keeps going with the hope that someday the trapdoor or the light ray might come again. Great Hope!!
One day, it happens!! The trap door opens again for the food to be sent in. The man manages to whisper loudly enough saying, “Look, can you help me out? I have been trying to go up for long”.
As luck would have it, he sees a strong arm descending from the hole. He holds it and scrambles up and is soon outside the door, outside the tunnel.
There’s a big commotion downstairs. Everybody says, “What’s happened to this man, Bob? Bob!–let’s call him (that).
“He’s disappeared suddenly. We saw him ascending and he’s no more with us. And, we heard the sounds. And, he broke that which kept us together. He’s a rebel for he has broken the chain that kept us together. He is outside the chain now.”
But, that’s all they know. Beyond that, they don’t know that he was seen to go up and he has disappeared and he is no longer coming. He no longer is visible.
Now, while he is going up, he is warned to keep his eyes closed and to open the eyes gradually. Otherwise, in the full blast of the light, he might go blind.
