1. There is a clear definition in the Indian yoga classic Yoga (One) Sutra: identifying wisdom is a way to eliminate the combination of seeing and seeing and lead to liberation. Through the practice of various branches of unity, impurities are gradually reduced, and the light of knowledge will illuminate the ability of identification. Eight branches of unity: external law, internal law, physical adjustment, pranayama, sensory control, concentration, ecstasy and integration. This identification wisdom goes through seven branches and reaches the last one.
2. Reality is universal, and meditation is universal. Reality is prajnaparamita, that is, observing all the truth and absoluteness of the environment with prajnaparamita wisdom; Although this is not prajna, it can be the root of prajna, so it is called prajna; By observing Prajna, we can observe the true and absolutely realistic wisdom of all laws.
3. Universal, universal. Prajna in the world, that is, secular and relative prajna; Out-of-bounds Prajnaparamita means ultra-secular and absolute Prajnaparamita. It is also the reality of prajnaparamita, and it is prajnaparamita. If you add convenient prajnaparamita or write prajnaparamita, it is called three prajnaparamita. Convenient Prajna is the relative wisdom to understand the differences between methods based on reasoning and judgment; Prajna paramita sutra system includes prajna paramita sutra and prajna paramita sutra.

Prajnaparamita wisdom includes six kinds, namely, the so-called six Prajnaparamita, the first is Prajnaparamita in reality, the second is Prajnaparamita in realm, the third is Prajnaparamita in writing, the fourth is Prajnaparamita in convenience, the fifth is Prajnaparamita in family, and the sixth is Prajnaparamita in observation. The connotation of six kinds is Vajrayana Prajna.
