A Study on Zhu dan Xi's "Theory on the Sufficiency of Yang and the Deficiency of Yin"

주단계(朱丹溪)의 "양유여음불족론(陽有餘陰不足論)"에 관한 연구(硏究)

"Theory on the Sufficiency of Yang and the Deficiency of Yin(陽有餘陰不足論)" mainly instituted as follows: The 'Yang Qi(陽氣)' of the heaven(天) has changed to 'Qi(氣)', and the 'Yin Qi(陰氣)' of the earth(地) has changed to 'Xue(血)', 'Qi(氣)' is always sufficient and 'Xue(血)' is always deficient. 'The Always Sufficient Qi(氣常有餘)' means 'the fire always exists(常有火)', and 'the fire(火)' is 'the premier fire(相火)'. 'The premier fire(相火)' is always in men's body and causes 'activities(動)' which is the core characteristic in men's life, and in other side it always has opportunities to be made symptoms by 'the abnormal activities of the premier fire(相火妄動)'. In 'the always deficient Xue(血常不足)' , 'Xue(血)' is the 'Yin Qi(陰氣)' of liver and kidneys[肝腎] which is attached by 'the premier fire(相火)', as it means 'Xue(血)' and 'Jing(精)'. He suggested that 'the premier fire(相火)' is the power of human life, but if 'the premier fire(相火)' is not based on 'Yin Qi(陰氣)', it can not fulfill its function. So he thought that the maintenance and fulfillment of 'Yin Qi(陰氣)' is very important. In conclusion, "Theory on the Sufficiency of Yang and the Deficiency of Yin(陽有餘陰不足論)" explains the basic character of men's life which 'Dong Duo Jing Shao(動多靜少)', so 'the premier fire(相火)' which control 'the activities(動)' is always being and 'Jing Xue(精血)' which control 'Jing(靜)' is always scare.
