초간본 『이참봉집』에 나타난 이광려 학술사상과 실학정신(2)

Abstract

Yi Kwangryeo’s Sincere Mind is metaphysical reality and a Moral Mind. Practical Learning is the realization of the Sincere Mind in daily life. Yi Kwangryeo focused on how to practice Sincere Mind in life rather than an interpretation of a Sincere Mind. Yi Kwangryeo suggested making Simui(深衣), growing sweet potatoes, and Gache(加髢) and Gyeryu(笄禮) as concrete ways to practice losing heart. Simui can be worn as casual wear but is also a Traditional Shroud(壽衣). Yi Kwangryeo wrote in Hangeul to spread the method of making Traditional Shroud, which was considered the exclusive property of Sadeabu, to people who do not know Chinese. Sweet potato is famine relief crop. As a way to save the poor people suffering from hunger, Yi Kwangryeo thought of cultivating sweet potatoes. So, sweet potato seeds were obtained from the southern provinces and spread throughout the country. Gache is a decorative piece of hair worn by women to make them look thicker. However, the price of Gache was too high, and the harm was very serious. Yi Kwangryeo encouraged a frugal lifestyle by suggesting a way to curl up your hair. Gyeryu is a woman's coming-of-age ceremony. However, Guanryu, the coming-of-age ceremony for men, is always performed, but for women, rites are not performed. Yi Kwangryeo saw this as disrespect for women. As mentioned above, Yi Kwangryeo encouraged the people to live a frugal life through Simui and Gache. In addition, He(Yi Kwangryeo) tried to provide food and shelter for the people through sweet potatoes and bricks. Through Gyeryu, He tried to seek gender equality. This is what it means to ‘love the people.’ Loving the people is a Sincere Mind, the Sincere Mind is to love the people.
