What was the root cause of the conflict between the two brothers in their previous life, according to the story Baba told?

According to the story shared by Sai Baba in Chapter 46, the root cause of the conflict was a 'terrible greed for wealth' that arose from 'a difficult combination of karma and circumstances.' Although the two brothers initially had great love and unity, this greed created enmity between them. The elder brother's 'vision was blocked by the delusion of wealth,' leading him to forget their bond and even become ready to kill his sibling. The text describes the force of greed as 'uncontrollable,' ultimately causing them to fight like enemies and murder each other, which led to their rebirth as goats.
