What is the connection between one's past karma and attaining the company of a saint, as explained in Chapter 28?

Chapter 28 teaches that a profound connection exists between one's past actions and spiritual opportunities. It states that when the accumulated karma of many births rises up, only then does one attain the company of saints. This sacred meeting is a pivotal event that destroys the "darkness born of delusion." According to the chapter, this encounter ignites the fire of discrimination, causes detachment from worldly enjoyments, and ultimately destroys the accumulated karma, leading to a successful and liberated life.
