 The importance of self-exertion and service to humanity in one's spiritual life is emphasised further in Baháʼu'lláh's writings, where he states that work done in the spirit of service to humanity enjoys a rank equal to that of prayer and worship in the sight of God.Most Baháʼí meetings occur in individuals' homes, local Baháʼí centers, or rented facilities.Worldwide, as of 2018, ten Baháʼí Houses of Worship, including eight Mother Temples and two local Houses of Worship have been built and a further five are planned for construction.
