Ghasidas

Ghasidas (1756–1850) also known as Guru Ghasidas, was Guru (teacher) of the Satnampanth in the early 19th century. The Satnami sect is similar to Sikhism. It was Guru Ghasidas who decided to start treating everyone the same in a deep forested part of Chhattisgarh, India.
Ghasidas was born on 18 December 1756 in Girodpuri, District – Balodabazar. Guru Ghasidas was the son of Mahngu Das and Amrotin Mata. Ghasidas preached Satnam particularly for the people of Chhattisgarh. After Guru Ghasidas, his teachings were carried on by his son, Guru Balakdas. Guru Ghasidas was the founder of the Satnami community in state of Chhattisgarh. During his lifetime, the political atmosphere in India was one of exploitation. Ghasidas experienced the evils of the caste system at an early age, which helped him to understand the social dynamics in a caste-ridden society and reject social inequality. To find solutions, he travelled extensively across Chhattisgarh.
Saint Guru Ghasidas established Satnami community in Chhattisgarh, India based on "Satnam" (meaning "Truth") and equality. The Guru's teachings and philosophy is similar to sikhism. Guru Ghasidas created a symbol of truth called "jaitkhambh" – a white painted log of wood, with a white flag on the top. The structure indicates a white man who follows the truth "satnam" is always steadfast and is the "pillar of truth" ("satya ka stambh"). The white flag indicates peace.
