The Vedic hymn known as Kama-gayatri describes the face of Krsna as the king of all moons. In metaphorical language, there are many different full moons, but they are all one in Krsna. There is the full moon of His face, the full moons of His cheeks, the full moon of the sandalwood-pulp spot on His forehead, which is a half-moon, and the beautiful full moons of His fingernails and toenails. In this way there are twenty-four and a half moons, and Krsna is the central figure of all of them.
