Part 2 - Purification Of Mind

The second purification is Purification of Mind (Citta visuddhi). If we want to attain insight knowledges, the mind must be purified from all kinds of defilements. When the mind is well concentrated on any mental or physical phenomena, it is free from all these hindrances. This is known as purification of mind - Citta visuddhi. With this purification, the mind can penetrate into the mental and physical processes in their true nature. First of all, he distinguishes between mental process and physical process (nama and rupa) through his own experience. That is known as Namarupapariccheda nana - knowledge of the difference between mentality and physicality.
