what evidence can you find that siddhartha is beginning to undergo a new process of rebirth?

As Siddhartha leaves the Buddha, he realizes that a change has overcome him: he has outgrown the desire for teachers. From teachers he had sought to discover the mystery of his Self. As Siddhartha says, "Truly, nothing in the world has occupied my thoughts as much as the Self, this riddle, that I live, that I am one and am separated and different from everybody else, that I am Siddhartha" (38).
