Eshu is the messanger of the orishas, the wind spirit. Can you catch the wind? Never, as like Eshu. He is also the more 'human' of the orishas, and like partys and dances, but because he is very crazy, when the candombles partys begins they sing a song to make him go away happy and don't spoil the party. According some legends, he loved to be among the human beings, and make sons and daugthers called eshus and pombagiras in the Umbanda. In a wrong interpratation, he are compared with the devil, and it's only because of his figure, Eshu has nothing bad agais him, and is not evil indeed.
