The marital status of Ganesha varies widely in mythological stories and the issue has been the subject of considerable scholarly review. Several patterns of associations with different consorts are identifiable. One pattern of myths identifies Ganesha as an unmarried brahmacārin with no consorts. Another mainstream pattern associates him with the concepts of Buddhi (intellect), Siddhi (spiritual power), and Riddhi (prosperity); these qualities are sometimes personified as goddesses who are considered to be Ganesha's wives. Another pattern connects Ganesha with the goddess of culture and the arts, Sarasvati. In the Bengal region he is linked with the banana tree, Kala Bo (or Kola Bou). Usually Ganesha's consort is portrayed as his shakti, a personification of his creative energy.
