Buddhism – India's Eternal Light of Wisdom

A complete guide for UPSC, SSC, and State PCS aspirants

👑 Gautam Buddha: The Man Who Awakened the World

Born in 563 BCE in Lumbini, Siddhartha Gautama was a prince of the Shakya clan. He lived a sheltered life until one day, he encountered the Four Sights: an old man, a sick person, a corpse, and a wandering monk.

Shocked by human suffering, he left his luxurious life behind in an event known as Mahabhinishkramana. After years of intense meditation, he attained Enlightenment under the Bodhi tree in Bodh Gaya at the age of 35 and became the Buddha — the Enlightened One.
