Celibacy (from Latin , cælibatus" ) is the state of voluntarily being unmarried, sexually abstinent , or both, usually for religious reasons.     It is often in association with the role of a religious official or devotee.  In its narrow sense, the term celibacy is applied only to those for whom the unmarried state is the result of a sacred vow , act of renunciation, or religious conviction.   In a wider sense, it is commonly understood to only mean abstinence from sexual activity.  
The English word celibacy derives from the Latin caelibatus , "state of being unmarried", from Latin caelebs , meaning "unmarried". This word derives from two Proto-Indo-European stems, * kaiwelo- "alone" and * lib(h)s- "living". 
In the religious movement of Brahma Kumaris , celibacy is also promoted for peace and to defeat power of lust and to prepare for life in forthcoming Heaven on earth for 2,500 years when children will be created by the power of the mind even for householders to like holy brother and sister.
