What is Prajna wisdom?
It involves the six sense organs and the corresponding six dusts: seeing forms with the eyes, hearing sounds with the ears, etc. Prajna wisdom is when these sensory perceptions are clear, yet one is not moved by them and the mind does not make distinctions. Analogously, a mirror can create a reflection of all things, whether they are mountains or water. As they come and go, their reflections also come and go. It is the same with people and all phenomena. A person with Prajna wisdom perceives them clearly, but their coming and going will not cause this person to give rise to hatred, love, suffering or joy.
