How does the description of the fig tree garden highlight siddharthas mood

In terms of actual writing, Hesse's language is remarkably simple. Take the first sentence for example: "In the shade of the house, in the sunshine on the river bank by the boats, in the shade of the sallow wood and the fig tree, Siddhartha, the handsome Brahmin's son, grew up with his friend Govinda" (3). The sentence structure is uncomplicated, just a string of descriptions linked list-like by commas. The Fig tree represents unchanging calm which Siddhartha strives for.
