First of all, you copied a word wrong, which makes the meaning unclear. The original text should be like this: Hold the green yang in your hand and plant it in the field. When you lower your head, you can see the sky in the water. The six pure roots are the way. Going back is actually going forward. This should be a greeting from Budai monk in the Tang Dynasty. To write it, let’s first look at the meaning of each sentence.
"Planting green rice seedlings all over the field, lowering your head and seeing the sky in the water" is a description of When a farmer was planting rice, he planted handfuls of green rice all over the field. He looked down and saw the blue sky floating on the water, and he also saw himself!
A common problem among ordinary people is that they only see the shortcomings of others and cannot see their own faults. The sky in the water is like a mirror. People must realize themselves consciously and make their true nature clear and visible. Only then can "the six roots be pure before they can be the Tao", so that their eyes, ears, nose, tongue, body, and mind will not be affected by external colors, sounds, If the six dusts of smell, taste, touch, and Dharma are polluted, maintaining the purity of one's own nature at all times is the Tao and practice.
"Regressing turns out to be moving forward", which is quite philosophical. Just imagine, a farmer is planting rice seedlings. While planting green rice seedlings, he steps back step by step until he returns to the edge of the field. Only then has a field of rice seedlings been planted. It seems like he is retreating but actually making progress. Sometimes, giving in is not completely negative, but a positive change. When we get along with others, what can we achieve by arguing over everything, ostracizing and slandering each other? It is better to take a step back and seek greater success.
So, I personally believe that we should strictly demand ourselves, find subjective reasons in advance, and constantly improve ourselves.
