Madurai Meenakshi (Goddess Parvati) is depicted with a green body color. This is because she represents moola prakriti or in simple terms primordial nature. She is the personification of Mother Nature – everything is born, lives and undergoes transformation in her. Life begins and ends in her. As Green is the color of life she is depicted having a green body color.
Without mother there is no life. Without life there is nothing in this universe. It is because of her blessing that there is life and there is food to nourish and sustain life. Green color represents both life and food. Thus Madurai Meenakshi unites with Shiva (Purusha) and life begins. She sustains all life forms until each life form transforms to another form (which we ignorantly refer as death). There is no end in pure nature there is only transformation. One becomes food for another and life continues. All this happens when Goddess Madurai Meenakshi wishes.
The murti of Mother Goddess Madurai Meenakshi worshipped in the world famous the Meenakshi Amman Temple in Madurai, Tamil Nadu, is carved from Marathakam or emerald (bluish green color gemstone).
