Sikh devotees are taking a selfie on the birthday anniversary of the tenth and last Sikh guru Gobind Singh with Sikh's holiest shrine in Amritsar, India, in the background.
Gobind Singh (1666—1708) was also a warrior and a poet, and is considered a philosopher who followed the theory of the Just War (the war should start only after all other possibilities for agreement have been exhausted; the war should be fought without hatred and the feeling of revenge; without wanting to have profit; may be started only by idealists, but not by mercenaries, the warrior should fight without fear, be sure of the victory and not think about the consequences.)
