Prajna is the truth that governs the universe, the myriad things, society, and life. This truth is contained in everything. Thus, it is difficult to find it from the outside. We must search for prajna in our mind, which is closest to us. We must then use it to extinguish defilements and idle thoughts, do away with desires, and train the mind in mercy, wisdom, and liberation in order to reach the other shore, in other words, to become a buddha. This process is called the profound prajna practice.
