Step 1: Definition of Nirvāṇa.
Nirvāṇa signifies the absolute end of suffering, craving, and the cycle of rebirth. It represents the ultimate objective in Buddhism.
Step 2: Ubiquity of the Concept.
Every Buddhist tradition, including Theravāda (Hinayāna) and Mahāyāna, recognizes Nirvāṇa as the supreme emancipation.
Step 3: Examination of Different Perspectives.
- Mahāyāna adherents: While acknowledging Nirvāṇa, they integrate it within the broader Bodhisattva ethos.
- Jain followers: They practice Moksha, distinct from the Buddhist concept of Nirvāṇa.
- Theravāda adherents: They prioritize individual achievement of Nirvāṇa through Arhatship.
- All Buddhist instructors: Confirmed, Nirvāṇa is a universally accepted principle across all Buddhist doctrines.
Step 4: Final Determination.
Consequently, the assertion "the ultimate cessation of suffering is Nirvāṇa" is attributed to all Buddhist instructors.
