in this, that he loves his country; let him rather glory in this, that he loves his kind." After a short illness, Baháʼu'lláh died on 29 May 1892 in Bahji. He was buried adjacent to the mansion in an existing building which now serves as his shrine. It is a place of pilgrimage for Bahá’ís from all over the world, and is the Qiblih they face for daily obligatory prayers. In 2008 the shrine of Bahá’u’lláh, along with other Baháʼí holy places in ‘Akká and Haifa, were added to UNESCO's list of World Heritage Sites. Teachings God The Baháʼí concept of God is monotheistic. God is a single uncreated imperishable entity that is the absolute and ultimate source of all existence.

Bahá’ís believe manifestations reflect the light of God's Will and Purpose in this world. Bahá’í writings liken manifestations to perfect mirrors reflecting one sun—though every mirror is distinct yet the reflection cast by each is of the same sun, varying only due to differences relating to time and position. Bahá’u’lláh says the guidance of manifestations necessarily differ due to the particular situations and requirements of those they deal with:"The Prophets of God should
