Mental health is a term used to describe either a level of cognitive or emotional wellbeing or an absence of a mental disorder. From perspectives of the discipline of positive psychology or holism mental health may include an individual's ability to enjoy life and procure a balance between life activities and efforts to achieve psychological resilience.
The World Health Organization states that there is no one "official" definition of mental health. Cultural differences, subjective assessments, and competing professional theories all affect how "mental health" is defined.

 Cultural and religious considerations
Mental health can be socially constructed and socially defined; that is, different professions, communities, societies and cultures have very different ways of conceptualizing its nature and causes, determining what is mentally healthy, and deciding what interventions are appropriate. Thus, different professionals will have different cultural and religious backgrounds and experiences, which may impact the methodology applied during treatment.
Many mental health professionals are beginning to, or already understand, the importance of competency in religious diversity and spirituality. The American Psychological Association explicitly states that religion must be respected. Education in spiritual and religious matters is also required by the American Psychiatric Association.
