What are the motifs in Lord of Light by Roger Zelazny?

Love or a "love triangle " is an important motif.

Three of the main characters in "Lord of Light," Sam, Kali and Yama, are connected in a "love triangle" that adds extra significance to their interactions and raises possibilities that their motives are affected by this relationship. The author does not reveal the full extent of their connections until the last third of the book, which casts earlier events in a new light and adds depth to the story.
