What metaphors are used in Chapter 3 to convey the nature of Sai's grace and the power of his stories?

The author of Chapter 3 uses several poignant metaphors to describe Sai's grace. Sai's compassion is likened to that of a 'motherly cow' who feels a surge of milk for her calf, illustrating that His love and grace flow naturally and unstintingly towards His devotees. Expanding on this, Sai is also depicted as a 'cloud of joy' that rains down to satisfy the spiritual thirst of the devotee, who is compared to a 'Chataka bird' waiting eagerly for this downpour. The stories themselves are called the 'nectar of saints' stories,' a divine substance that can free one from worldly cravings and destroy sins, emphasizing their purifying and life-giving power.
