Summary: Guru Arjan compiled the Adi Granth, the central object of Sikh worship, including works of 16 Hindu Bhaktas and Muslim saints, which became the source of Sikh prayer and wisdom. Guru Har Gobind initiated a military career and armed resistance, leading to his arrest by Jehangir, but his followers continued to support him. Guru Gobind Singh, a great revolutionary leader, created the Khalsa to resist tyranny and oppression, infusing in them a spirit of fearlessness and self-sacrifice. His method of self-defense through arms was a departure from the pacifist policies of his predecessors, revitalizing Sikhism as a revolutionary force in India. His battles against the Mughal Empire and efforts to create a united front against persecution showcased his remarkable leadership and courage, striving for independence and righteousness. Ultimately, Guru Gobind Singh's legacy as a saintly warrior, Nation-builder, and embodiment of self-respect and bravery has left an indelible mark on Sikhism.
