“Remain true to our original aspiration and keep our mission firmly in mind” is a theme education practice carried out by our Party in the new era, which contains profound theoretical logic, historical logic and practical logic. The triple logic profoundly answers the fundamental questions of “who I am, where I come from, where I want to go”, and forms an organic unity. According to the inherent requirements of these three logics, the historical experience and realistic enlightenment of the Party’s thematic education practice are further summarized and revealed. It is concluded that the theme education practice should be carried out closely around the Party’s central task, and that we must strengthen Marxist theory, persist in integrating theory with practice, and strive to solve prominent problems within the party, persist in combining holistic education with key education, explore and establish longterm mechanism, consolidate and expand the fruit of education, and always maintain the advanced nature and purity of the party. This paper further profoundly expounds the promotion path of “remain true to our original aspiration and keep our mission firmly in mind”, that is, innovating ideological education, strengthening theoretical arm, and strengthening ideals and beliefs, carrying forward the spirit of revolution and struggle, and refining the act of responsibility, establishing and perfecting longterm mechanism of Party construction. 
