The main Hindu Gods are
- The formless Brahman, the creator who is both immanent and trancendent in all of creation. (Perhaps it is easier to say that all creation exists in God. That is what Brahaman means.)
- There is a trinity of Creator, Preserver, Destroyer. Gods are Brahma (not Brahman), Vishnu, Maheswara (or Shiva).
- There are consorts to the Gods. Saraswathi is consort to Brahma; Lakshmi is consort to Vishnu; Kali is consort to Shiva.
- There are the mother Goddesses, Devi, Durga, Parvathi, Mahalakshmi, Mother Ganga, Mother India, and Bhoomi Devi, Mother Earth.
- The sun, the moon and the four elements are Gods. The Sun is God Savitri, the moon is God Chandra, God Vayu is the God of rain, Varuna is the god of Wind, Agni is the god of fire, and the Earth is the mother Goddess, Bhoomi Devi.
- Other gods include Ganesha and Murugan (sons of Shiva and Parvathi), Hanuman (a varnar - extinct race of intelligent tree dwellers) who achieved immortality in the service of Rama, and Gayathri, the great protector.
There are incarnations of God. These are called Avatars, and there are ten avatars and many part avatars in Hinduism. Jesus, for example, is a Avatar of Love (premavatar) in Hinduism, a descent of God filled with Divine Love.
The main avatars, the human forms of God are Rama, Krishna and Sai Baba. Other incarnations include Chaitanya and Mahavatar Babaji.
There are also dasavatars, incarnations of God in specific forms to combat evil. These have been Matsya, the fish, Kurma, the toitose, Varaha, the boar, Narasimha, the half man-half lion, Vamana, the Dwarf, and Parasurama, Rama with the Axe.
Gautama Buddha is one of the ten avatars, an incarnation of God, in Hinduism.
There have been other incarnations of God into human form, for example, Anandamayi Ma, Mother Meera, Ammachhi, Sathya Sai Baba, and Lord Dattreya has taken human avatara many times.
