The present paper proposes systematic mindfulness focusing on mindfulness of the emotion as a method of stress management. Systematic mindfulness is an integration of traditional mindfulness meditation and modern stress management. The former pursues the change of the mind with intuitive understanding of it, and the latter pursues the change of the mind with analytic understanding of it. Emphasizing the importance of complementary integration of both methods for holistic understanding and change of the mind, systematic mindfulness is proposed. The present paper also discusses the merits of systematic mindfulness for stress management.
