Can you explain the metaphors of the ocean, the Kalpataru, and the sun used in the text to describe the abundance of Sai's stories?

In Chapter 47, the author uses several powerful metaphors to illustrate the inexhaustible nature of Sai's stories and wisdom. Firstly, he says, "We are sitting on the shore of the ocean of Sai's stories," which conveys a sense of boundless, immeasurable depth and supply. Secondly, he invokes the Kalpataru, the mythical wish-fulfilling tree, stating that under its shade, a desire is fulfilled as soon as it arises, implying that any story or spiritual lesson needed is instantly available. Lastly, the author asks, "In the house of the Sun, who worries about a lamp?" This metaphor positions Sai as the ultimate source of spiritual light, making any other source of illumination (or stories) redundant. Together, these images emphasize that with Sai as a protector, there is an endless supply of the "nectar of stories" to be enjoyed.
