The most important figure of Seon in the Goryeo was Jinul. In his time, the sangha was in a crisis of external appearance and internal issues of doctrine. Buddhism had gradually become involved with secular affairs, incorporating practices such as fortune-telling and offering of prayers and rituals for success in secular endeavors. Inclination toward these practices resulted in the profusion of an increasingly larger number of monks and nuns with questionable motivations. The correction, revival, and improvement of the quality of Buddhism became prominent issues for Buddhist leaders of the period.
