Pancha means Five and mukhi means faced. He is considered as the ‘god of gods’. Just the single-headed elephant god can bestow umpteen benefits on the worshipper. But imagine, if you were to worship a five-headed elephant god – the Panchamukhi Vinayaka.
Annamaya kosha: the flesh body made of matter
Pranamaya kosha: the breath body, or energy body
Manomayakosha: the mental body
Vighnnamayakosha: the body of the Upper Consciousness
Anandamayakosha: the body of Cosmic Bless.
Thus this form of Lord Ganesha when kept in home/office, brings auspicious vibrations of spirituality, harmony and bliss.
