Theory:

     As they neared the village the child could see many other footpaths full of throngs, converging to the whirlpool of the fair, and felt at once repelled and fascinated by the confusion of the world he was entering.
 
     A sweetmeat seller hawked, “gulab-jaman, rasagulla, burfi, jalebi,” at the corner of the entrance and a crowd pressed round his counter at the foot of an architecture of many coloured sweets, decorated with leaves of silver and gold. The child stared open-eyed and his mouth watered for the burfi that was his favourite sweet. “I want that burfi,” he slowly murmured. But he half knew as he begged that his plea would not be heeded because his parents would say he was greedy. So without waiting for an answer he moved on.
Explanation:
  
As they were about to reach the fair, the child saw a huge crowd of people walking from all directions towards the fair. The heavy crowd alarmed him, and he stood there for a while, but the next moment, he got attracted to the breathtaking crowd of humanity.
 
At the entrance of the fair, in a corner, a sweetmeat seller had set up a shop. He was selling various sweets like gulab jamun, rasgulla, burfi, and jalebi. The sweets were exhibited at different heights and were covered with foils of gold and silver. The boy's mouth watered when he saw his favourite burfi. He expressed his desire to get one in a low voice because he knew that his parents would disapprove his request. They would say that he was greedy for the burfi. As he did not expect anything from his parents, he walked further.
