Between heaven and earth, the growth of all things depends on the source of carbon and nitrogen. Carbon is the cornerstone of life, such as the trees of the forest and the stems of grass. They all contain carbon to form their forms. It is as indispensable to all things as the beams and pillars are to the vast buildings.

Nitrogen is also heavy. If the soil is full of nitrogen, the seedlings will thrive and the leaves will be lush. And nitrogen enters all things, turns into protein, and is essential for vitality.

Watching the man's nature, carbon and nitrogen flow, and the cycle is endless. Plants absorb carbon in gas, absorb nitrogen in the soil, and through the wonders of photosynthesis, turn it into their own use. Then, either for eating other things, or for decaying and returning to the soil, the quality of carbon and nitrogen, and then enter the cycle.

Therefore, if you want to nurture all things, you must check the source of carbon and nitrogen. If you are good at adjusting it, things will be prosperous; if you are contrary to it, your vitality will decline. When you take the source of carbon and nitrogen as the foundation, follow the path and make the best use of it, you can get the magnificent scenery of all things flourishing.
