Guru Hargobind introduced the process of militarization to Sikhism, likely as a response to his father's execution and to protect the Sikh community. He symbolized it by wearing two swords, representing the dual concept of miri and piri (temporal power and spiritual authority). In front of the Harmandir Sahib in Amritsar, Guru Hargobind constructed the Akal Takht ("the throne of the timeless one"). The Akal Takht represents the highest seat of earthly authority of the Khalsa (the collective body of the Sikhs) today.
