Step 1: Understanding Nāgasena.
Nāgasena was a Buddhist philosopher and monk, famous for his dialogue with King Milinda (Menander I) recorded in the text “Milindapañho.” This work contains discussions on Buddhist philosophy, rebirth, and karma.
Step 2: Rebirth theory in Buddhism.
Rebirth is one of the fundamental doctrines in Buddhism. It means that beings are reborn again and again in the cycle of saṃsāra due to karma and ignorance.
Step 3: Nāgasena’s view.
In “Milindapañho,” Nāgasena clearly accepted the rebirth theory. He explained that while there is no permanent soul (anātman), the continuity of consciousness and karmic forces cause rebirth. He used the simile of lighting one lamp from another to explain how rebirth happens without a permanent self.
Step 4: Eliminating other options.
- (1) Not accepted → Incorrect, because Nāgasena strongly defended rebirth.
- (3) Neglected → Incorrect, because he elaborated in detail on rebirth.
- (4) Remained silent → Incorrect, because he gave metaphors and arguments.
