The Hindu god that some call Ganesh and I call Ganesha, because that is the name considered as right spelling, is one of the most beloved gods in the Hinduism! He is the son of the two other well loved gods named Shiva and the wife of Shiva, Parvati. Ganesha is a god that symbolizes wisdom and intelligence.
As mentioned Ganesha symbolizes wisdom and intelligence. As well as those highly appreciated qualities he is also worshiped for education, knowledge and wealth, maybe that is why he is so popular? Another question that is often asked is why the human body of Ganesha is paired with the head of an elephant? The answer most relevant judged by the popularity is the story mentioning Ganesha being created by Goddess Parvati as a guardian to her privacy:
Incensed by the refusal of her husband to respect her privacy, to the extent of entering her private chambers even while she was having her bath, Parvati decided to settle matters once and for all. Before going for her bath the next time, she rubbed off the sandalwood paste on her body and out of it created the figure of a young boy. She infused life into the figure and told him he was her son and should guard the entrance while she bathed.
Soon after, Shiva (Lord of destruction and husband of Parvati) came to see Parvati but the young boy blocked his way and would not let him in. Shiva, unaware that this lad was his son, became furious and in great anger fought with this boy whose head got severed from his body in the ensuing battle. Parvati, returning from her bath, saw her headless son and threatened in her rage to destroy the heavens and the earth, so great was her sorrow.
Shiva pacified her and instructed his followers (known as ganas) to bring the head of the first living being they encounter. The first creature they encountered was an elephant. They thus cut off its head and placed it on the body of Parvati’s son and breathed life into him. Thus overjoyed, Parvati embraced her son.
The one naming Ganesha was his father Shiva. The name or word is made up of the name of Shiva’s followers, gana, and the word for lord, isha. As well as passing this mighty name he also appointed Ganesha to be the lord of his ganas.
