Step 1: Concept of Nirvāṇa.
Nirvāṇa means the complete cessation of suffering, desire, and rebirth. It is the final goal of Buddhism.
Step 2: Universality.
All Buddhist schools — whether Theravāda (Hinayāna) or Mahāyāna — accept Nirvāṇa as the ultimate liberation.
Step 3: Analysis of options.
- Mahāyānis: They emphasize Nirvāṇa but in a broader Bodhisattva ideal.
- Jains: They also have Moksha, but not Nirvāṇa as in Buddhism.
- Hinayānis: They focus on personal attainment of Nirvāṇa (Arhatship).
- All Buddhist teachers: Correct, Nirvāṇa is universally accepted across all Buddhist traditions.
Step 4: Conclusion.
Thus, the concept “ultimate cessation of suffering is Nirvāṇa” belongs to all Buddhist teachers.
