1. Thus have I heard. On one occasion the Blessed One was living at Savatthi in Jeta's Grove, Anathapindika's Park.
Then Subha the student (brahman), Todeyya's son, went to the Blessed One and exchanged greetings with him, and when the courteous and amiable talk was finished, he sat down at one side. When he had done so, Subha the student said to the Blessed One:
2. "Master Gotama, what is the reason, what is the condition, why inferiority and superiority are met with among human beings, among mankind? For one meets with short-lived and long-lived people, sick and healthy people, ugly and beautiful people, insignificant and influential people, poor and rich people, low-born and high-born people, stupid and wise people. What is the reason, what is the condition, why superiority and inferiority are met with among human beings, among mankind?"
3. "Student, beings are owners of kammas, heirs of kammas, they have kammas as their progenitor, kammas as their kin, kammas as their homing-place. It is kammas that differentiate beings according to inferiority and superiority."http://www.accesstoinsight.org/lib/auth ... ml#shorter
