This article shows that social work practice can be carried out on ecological and spiritual levels in alignment with Korean society’s unique naturalistic principles, instead of blindly following Western ideological systems in approaching spirituality in socal welfare fields. According to spiritual teachings of Donghak-Chondokyo, it is important to awaken the divine nature within oneself and realize that all beings are connected in oneness to be able to see the universe and human-beings in a new light. If one were to follow universal spiritual teachings of Donghak-Chondokyo, daily practices of wholistic perspectives on life in all areas becomes important. In particular, based on the spirituality of ‘deification/adoration(모심)’ and the principle of life, a spiritual community of ‘ecologically integrated comprehensive welfare’ may be pursued within which sustenance and energy can be attained independently, without dividing social welfare areas into diverse fields of practice. It is because Suwoon’s Donghak sees that the realization of one’s own individual dignity and connectedness of all lives and the restoration of deep innermost mind (inner self) should serve as newly restored life’s fundamental ontological foundation. From this perspective, the spirituality of Donghak-Chondokyo can act as ‘deep mind’s ecology’ most needed by social workers who must practice inner peace and sharing work, while overcoming many difficulties in social welfare fields in the Korean society.
