Who was the primary witness to Baba starting the grinding, and what was their initial reaction?

The primary witness described in the text was the narrator, who is later identified as Hemadpant. His initial reaction was one of pure astonishment and confusion. Chapter 1 states that his 'mind was filled with great wonder' upon seeing Baba, a detached saint with no possessions, suddenly begin to grind wheat. The narrator questions the purpose of this action, noting that in all his experience with saints, he had never seen one perform such a task. This feeling of wonder at the 'inconceivable cause and effect' was so profound that it ultimately inspired him to write a book about Baba's divine plays.
