Life is filled with obstacles and unhappiness. However Yemaya is the all-powerful mother of all, who desires happiness for her children and will do whatever she can to obtain it for them. To obtain joy and smooth sailing:
Go to the beach.
Dig a small pit in the sand.
Light white and/or blue candles. Make your petition.
Enter the water. Greet Yemaya in her guise as mermaid or as a beautiful woman rising up from the sea. Offer her seven white roses.
