"Inner Heaven and Earth?" Azure Dragon Star Lord pondered, "Is it using oneself as a heaven and earth?"
Lu Luanti nodded, "Emperor Xuanhuang believes that the human body is a microcosm of heaven and earth. The Tao gives birth to all things, heaven and earth are the greatest among things, humanity is the essence among things. Seeking from Tao, people align with heaven and earth, comparing the heart to heaven, the kidney to earth, the liver to yang, and the lung to yin.
Humans can cultivate an inner heaven and earth within the place where kidney water transforms into qi and flourishes. Thus, like heaven and earth, it runs endlessly, allowing longevity and strengthening over time. It's said this is a dharma gate created by the Primordial Emperor in response to the calamity of turbid qi. Though it can't achieve true indifference to external seeking, its demand on heaven and earth is far less, not even a percent of what the Eternal Gods require."
"I see."
