The idea of this research is simple – the work of the soul happens inside the body and depends on the body. Knowledge, imagination, intuition and other powers of the soul are connected to the body and are maintained through it. There are strong connections between the soul and the body the sound of which is tuned through diet and ascesis. Diet allows you to consciously participate in subtle movements of the soul, the body, thoughts and sensations. Without diet cognition is loose and unpredictable. A unified regime of soul and body allows one to take responsibility for one’s own life, fate andvisions. How is the work of the soul conducted, how does one work with the matter of the soul? How is the soul nourished? This research is a testimony to my preparation, a prologue to such work. All efforts were made to create conditions, foundations for working with the matter of the soul. In order for that to happen I took it upon myself to investigate disciplines of the soul. I looked to Vydūnas to find proven methods of nourishing one’s health. Vydūnas’ diet 2.0 is a condition, a method, a practice. It can only be understood by realising it through yourself. Its criticism and reflection only becomes possible through experiencing it in the body, thoughts, senses, consciousness, dreams. That is why the beginning of this new research was a description of the diet, recipes, its conditions, naming the principles, drawing up of daily regime. The research turned into performative writing – writing influenced by the diet.
