My task was to get out of that cavern before the golden light came on again.
The Gray Mahatma led the way to the door, and it was just as well that he did, for there was some secret way of opening it that I should almost certainly have failed to find.

I pushed him through ahead of me.
And then we were in pitch darkness.

There was neither light, nor room to turn, and nothing for it but for the Mahatma to lead the way along, and I had to be careful in carrying King not to injure him against the rock in the places where the passage narrowed.
However, he began to recover gradually as we neared the end of the long passage, regaining consciousness by fits and starts like a man coming out of anesthesia, and commencing to kick so that I had hard work to preserve him from injury.

When his feet were not striking out against the walls his head was, and I finally shook him violently.

That had the desired effect.
