“Hu Tu’s themes are Earth, nature, ecology and fertility. Her symbols are the globe, soil, all natural items and marble. Literally means ‘Empress Earth’, in Chinese mythology, this Goddess embodies and personifies the earth in spring and its fertility. Through Her we can learn how to live abundantly, while maintaining a reciprocity with nature. Hu Tu also teaches us how to see and integrate nature’s lessons.
According to tradition, this is the birthday of Hu Tu, in the form of Mother Earth. Celebrate it as you might any birthday, with a little twist. Make a fertilizer cake for the earth and light a candle on it. Blow out the candle, making a wish to Hu Tu for earth’s revitalization. Then, give the fertilizer to the soil to start the process!
This celebration bears may similarities to Earth Day in the West, so organize litter patrols, educate yourself on recycling techniques, take a long walk to truly enjoy Hu Tu’s beauty. As you walk, feel the sacredness of the ground beneath your feet and say a silent prayer of thankfulness to Hu Tu for Her care and providence.
Finally, make yourself a Hu Tu charm that stimulates grounding and draws figurative or literal fertility to you. Find any marble (blue is best) to represent Hu Tu. Cleanse and energize this today by putting it in rich soil to connect it to Hu Tu’s foundational energy. Carry the charm whenever you feel flighty or need to be more productive.”
(Patricia Telesco, “365 Goddess: a daily guide to the magic and inspiration of the goddess”.)
“While Hou Tu lay upon the Great Ocean She meditated upon the forms and powers within Herself and bore a great number of children, often without the aid of a consort. So rich was the Empress that life teems within and upon Her.” 
Hou T’u, or She, ‘princess of the earth’, was a Chinese fertility Goddess and patroness of earth’s abundance; thereby claiming the earth as Her symbolic element. Every village possessed a shrine, usually a mound of earth symbolizing the fertility of the soil, and in important towns there were larger mounds for the public celebrations. In the Forbidden City, Peking, near the Yung Ting Men or South Gate, stands the Altar of Agriculture, on whose terraces the emperor used to conduct the sacrifices to Her a on square marble altar at each summer solstice to invoke Her blessings and grace for a plentiful harvest and bring balance to the earth. Hou T’u’s domain is all earth magic, and the ceremonies and rituals performed in Her honor were believed to bring the people into resonance with their Divine Mother. Without this, the world would become cold and barren. So, here’s something to contemplate today; “How can I express my appreciation for all the gifts the earth provides?”
