This study sought to extract the principles and strategies of modern counseling from Wonhyo 's central idea. The central idea of Wonhyo can be compressed into one mind and two doors, which focuses especially on one mind. One mind is a place of mind that is one that is not divided into two, and in other words it is also called 'real self'. The researcher identified the real self as an entity that existed as Sunyata and explored the principles and strategies for meeting and enjoying the real self. In this process, we analyze the identity of ego in detail and suggest a desirable link between real self and ego. As a result, the basic principles of mooae counseling are summarized as recognizing real self as reality and encountering it, revealing the identity of ego, linking real self and ego. The basic principle of mooae counseling has been specified as a strategy to realize this again. Strategies to meet real self suggested 'meditation', 'flow', 'endless denial', and 'reminiscence'. The strategies to reveal the identity of the ego are presented as 'revealing the variability of the ego component', 'breaking the identity with the ego component', 'exposing the ego's acting relationship', and 'exposing the verbal reflex applied to the ego'. The strategy of linking real self and ego suggested 'moving the mind', 'participating in real self', 'presenting'.
