Goddess Kali wears a garland of skulls and a skirt of dismembered arms because the ego arises out of identification with the body. In truth we are beings of spirit and not flesh. So liberation can only proceed when our attachment to the body ends. Thus the garland and skirt are trophies worn by Her to symbolize having liberated Her children from attachment to the limited body. She holds a sword and a freshly severed head dripping blood. As the story goes, this represents a great battle in which she destroyed the demon Raktabija. Her black skin represents the womb of the unmanifest from which all of creation arises and into which all of creation will eventually dissolve. Depicted as standing on Shiva who lays beneath her with white skin in contrast to her black or sometimes dark blue skin. He has a blissful detached look. Sit back, relax and enjoy. Melt away stress, freshen up your aura and manifest your goals into reality. Establish the psychic link within yourself of spiritual awareness, inner peace, and positive transformation. You must pray daily and meditate on your desired result.
