Jerusalem, by virtue of the number and diversity of people who have held it sacred, may be considered the most holy city in the world. To the Jewish people it is Ir Ha-Kodesh (the Holy City), the Biblical Zion, the City of David, the site of Solomon's Temple, and the eternal capital of the Israelite nation. To Christians it is where the young Jesus impressed the sages at the Jewish Temple, where he spent the last days of his ministry, and where the Last Supper, the Crucifixion and the Resurrection took place. Also greatly venerated by the Muslims, it is where the prophet Muhammad ascended to heaven. While highly charged with intense religious devotion and visited by countless pilgrims and sages, Jerusalem has also been ravaged by thirty centuries of warfare and strife. It is a place of beauty and divinity, mystery and paradox; a sacred site which no modern spiritual seeker should fail to experience.
