Stemming from the highest Creator God called Brahman, prayer is focused on His many manifestations, including primarily Shiva and Vishnu. Some other extremely popular deities are Krishna and Rama (incarnations of Vishnu), Ma Kali (Mother Kali, the feminine deity, or Mother Goddess, aka Durga, Parvati, Shakti, etc.) and Ganesha (the famous elephant-headed God of wisdom). It is epitomised by the devotion of the God Hanuman or Bajrang Bali for his Lord Rama. Another major form of prayer for Hindus involves a heavy focus on meditation, through Hindu yoga that stills the mind in order to focus on God.
