Who is Lord Satyanarayan?

Who is Lord Satyanarayan? Satyanarayana is a form of Lord Vishnu. It is said that when Vishnu failed to get the end of the infinite pillar, Vishnu said the truth that he failed. Satisfied, Shiva gave the name of Satyanarayan to Vishnu (one who says the truth) and blessed him to have his own temples, idols, rituals etc. While Shiva cursed Brahma and Ketaki to never be worshipped and be neglected from all sacrifices and worships. Since then, Vishnu was as worshipped as Shiva and was famous as Satyanarayan.
