Concept of Cosmic Flow

Vaan was a man of great focus; the moment he was seated in the lotus position and closed his eyes, he immediately entered the perfect state of meditation – the state of emptiness. 

In this state, a person would not have any distracting thoughts, and their sense of the world would be heightened to the greatest extent as if they had become one with it.

Normally, people would have to practice for months or even years before they could achieve this mystical state. Even the experienced ones would still take half an hour of meditation before entering the state of emptiness.

Nevertheless, Vaan's state of emptiness was quite different from everyone else – he had thousands upon thousands of micro-thought processes in the back of his mind, constantly simulating scenarios and calculating probabilities.
