What the Buddha Taught – Paññā
Prajñā (Sanskrit) or paññā (Pāli) “wisdom” is insight in the true nature of reality, namely primarily anicca (impermanence), dukkha (dissatisfaction or suffering), and anattā (non-self). In addition, Abhidharma and later Mahāyāna text may include suññatā (Skt; Eng: emptiness). Source: Wikipedia
What is paññā? Paññā is direct knowledge. It is the excellent knowledge that leads us to liberation. Paññā is not the knowledge gained merely by reading books or by listening to discourses. It is actual knowledge that is gained through our own experience. By constantly practicing it, many unknown truths start manifesting themselves.
Even if one eradicates these unwholesome sankhāras at the surface of the mind by means of any meditation technique, yet one does not attain total liberation from the lower worlds.
However, when a meditator maintains the practice of objective awareness towards all bodily sensations, he develops a progressively stronger ability to be free from craving because by means of wisdom, he experiences the truth that every sensation is impermanent and constantly changing. He does not generate craving or aversion towards these sensations. Thus, his awareness and equanimity become stronger and stronger.
