Theory:

     Having run to and fro in a rage of running for a while, he stood defeated, his cries suppressed into sobs. At little distances on the green grass he could see, through his filmy eyes, men and women talking. He tried to look intently among the patches of bright yellow clothes, but there was no sign of his father and mother among these people, who seemed to laugh and talk just for the sake of laughing and talking.
 
     He ran quickly again, this time to a shrine to which people seemed to be crowding. Every little inch of space here was congested with men, but he ran through people’s legs, his little sob lingering: “Mother, Father!” Near the entrance to the temple, however, the crowd became very thick: men jostled each other, heavy men, with flashing, murderous eyes and hefty shoulders. The poor child struggled to thrust a way between their feet but, knocked to and fro by their brutal movements, he might have been trampled underfoot, had he not shrieked at the highest pitch of his voice, “Father, Mother!” A man in the surging crowd heard his cry and, stooping with great difficulty, lifted him up in his arms.
Explanation:
 
After some time he stood defeated. The loud cries turned into mild sobs. He saw some people standing and talking and tried to find if his parents were among them. The laughter and talks of the people were ridiculous for the child. He was searching for his parents.
 
The boy ran towards a temple which was crowded with people. He ran through the legs of men, calling out for his parents. The crowd was pushing each other as he neared the entrance of the temple. The boy got scared of huge strong men who starred people with their horrible eyes and pushed them with their strong and big shoulders. The boy could have been crushed under feet of men, and the boy cries out loud with a maximum pitch of his voice. A man in the crowd heard him and lifted the child with great difficulty.
