“In the Puja of Shri Ganesh you must bring the soft grass also, because [*]durvah, He’s fond of durvah, that’s called as durvah – because the soft grass is soothing to the eyes. Not only that, but it gives you the green part of the Swadisthana Chakra. Because He exists when we have not started about thinking, you have not started the thinking process. That suggests that part of Swadisthana, when you are not thinking, the green part of it; the lower part of the Swadisthana is green.
So the green is the one: at that stage we have not become human beings, at that stage it represents the green of Swadisthana, where it created the whole universe, everything. Up to that it’s green. Then when it starts creating the ego it becomes the yellow color, where it uses the sun, the action part – not “uses” the sun but becomes active, representing the sun side.
So the green represents actually the part of Ganesha, part of Ganesha in a way, because till then you are not thinking. You are at a level where you are close to the Mother Earth, you see. So the Mother Earth’s giving, you see. The sun part has not started when the green is there, because the Mother Earth gives this green. Of course the sun makes it green, that’s different point, but that you don’t start doing it. When you start doing something yourself at a human level, the whole thing becomes yellow. So Swadisthana has two sides, the physical and the mental side. The physical side is the green side, and the mental side is the yellow side.” – Shri Mataji, 22.08. 1982
