求翻译：我用《实践论》里的一句话作为我的结束语“通过实践而发现真理，又通过实践而证实真理和发展真理。从感性认识而能动地发展到理性认识，又从理性认识而能动地指导革命实践，改造主观世界和客观世界。”是什么意思？

I use the practice as a word in my closing statement "and discovering truth through practice, and confirmed truth and develop truth through practice. From the perceptual and dynamic development in the rational knowledge, and from the rational and dynamic way to guide the practice of revolution, subjective and objective world. ”
