Step 1: Understanding the Concept:
Alayavijnana is a sophisticated psychological concept used to explain the continuity of karma without a permanent soul.
Step 2: Detailed Explanation:
The Yogachara school (also called Vijnanavada or Mind-Only school) was founded by Asanga and Vasubandhu.
They introduced the idea of an 8th layer of consciousness called the "Storehouse Consciousness."
It stores the "seeds" (Bijnas) of past actions, which ripen into future experiences. This resolved the problem of how karma carries over across lifetimes when there is no permanent "self."
Step 3: Final Answer:
The concept of Alayavijnana belongs to the Yogachara school.
