Ajātivāda

Ajātivāda (अजातिवाद) is the fundamental philosophical doctrine of the Advaitin Hindu philosopher Gauḍapāda. According to Gauḍapāda, the Absolute (Brahman) is not subject to birth, change, or death. The Absolute is ajā, the unborn eternal. The empirical world of appearances is considered unreal, and not absolutely existent.

Gauḍapāda's perspective is based on the Māṇḍūkya Upanishad, applying the philosophical concept of ajāta to the inquiry of Brahman, showing that Brahman wholly transcends the conventional understanding of being and becoming. The concept is also found in Mādhyamaka school of Buddhist philosophy, as the theory of nonorigination.
