what was the main idea behind the daoist religion?

The main idea behind Daoist religion, also known as Taoism, is to follow and live in harmony with the natural flow and order of the universe, known as the Dao (or Tao). Daoism emphasizes the importance of non-action (wu wei) and simplicity, seeking to align oneself with the spontaneous and effortless way of nature. It promotes the cultivation of inner peace, tranquility, and connection with the Dao through practices such as meditation, qigong, and other techniques to balance and harmonize one's body, mind, and spirit. Daoism also incorporates the idea of immortality and the pursuit of longevity, as well as a reverence for nature and the understanding that all things are interconnected.
