Vishnu – Regarded as the sustainer, preserver and protector of the universe
Note: Vishnu is believed to return to earth in troubled times to restore the balance of good and evil. His worshippers called Vaishnava, consider him to be the greatest god. They regard the other gods as lesser or demi gods.
A fish I knew (Vishnu) was brilliant at calming things down in times of trouble. After it died, it appeared in the night sky to protect the universe.
