This is your imagination, but it's not. Wisdom is the wisdom of the world, not the wisdom of prajnaparamita; Buddha's prajnaparamita wisdom is fundamental wisdom, teacher-less wisdom and natural wisdom. This kind of wisdom is not obtained from the outside world, but everyone has it, only because of delusion and persistence, it covers up people's original wisdom. Although Sakyamuni Buddha can subdue delusion and persistence and prove to be Prajna, the purpose of learning Buddha is to practice according to the method of Buddha, so that everyone can develop their own Prajna wisdom, which is no different from Buddha.
