Quality of life (QOL) means a good life and we believe that a good life is the same as living a life with a high quality. This paper presents the theoretical and philosophical framework of the Danish Quality of Life Survey, and of the SEQOL, QOL5, and QOL1 questionnaires.The notion of a good life can be observed from subjective to the objective, where this spectrum incorporates a number of existing quality of life theories. We call this spectrum the integrative quality-of-life (IQOL) theory and discuss the following aspects in this paper: well being, satisfaction with life, happiness, meaning in life, the biological information system (“balance”), realizing life potential, fulfillment of needs, and objective factors.The philosophy of life outlined in this paper tries to measure the global quality of life with questions derived from the integrative theory of the quality of life. The IQOL theory is an overall theory or meta-theory encompassing eight more factual theories in a subjective-existential-objective spectrum. Other philosophies of life can stress other aspects of life, but by this notion of introducing such an existential depth into the health and social sciences, we believe to have taken a necessary step towards a new humility and respect for the richness and complexity of life.

It is possible to understand the process of healing from a holistic perspective. According to the life mission theory, we can stretch our existence and lower our quality of life when we are in crises, to survive and adapt, and we can relax to increase our quality of life when we later have resources for healing. The holistic process theory explains how this healing comes about: Healing happens in a state of consciousness exactly opposite to the state of crises. The patient enters the “holistic state of healing” when the (1) patient and (2) the physician have a perspective in accordance with life, (3) a safe environment, (4) personal resources, (5) the patient has the will to live, (6) the patient and (7) the physician have the intention of healing, (8) the trust of the patient in the physician, and (9) sufficient holding. The holding must be fivefold, giving the patient (1) acknowledgment, (2) awareness, (3) respect, (4) care, and (5) acceptance. The holistic process has three obligatory steps: (1) to feel, (2) to understand, and (3) to let go of negative decisions. This paper presents a theory for the holistic process of healing, and lists the necessities for holistic therapy restoring the quality of life, health, and ability to function of the patient.

When we acknowledge our purpose as the essence of our self, when we take all our power into use in an effortless way, and when we fully accept our own nature — including sex and sexuality, our purpose of life takes the form of a unique talent. Using this talent gives the experience of happiness. A person in his natural state of being uses his core talent in a conscious, joyful, and effortless way, contributing to the world the best he or she has to offer. Full expression of self happens when a person, in full acceptance of body and life, with whole-hearted intension, uses all his personal powers to realize his core talent and all associated talents, to contribute to his beloved and to the world. Thus, self-actualisation is a result of a person fully expressing and realizing his core talent.The theory of talent states that a core talent can be expressed optimally when a human being takes possession of a three-dimensional space with the axis of purpose, power and gender, as we have a threefold need: 1-Acknowledging our core talent (our purpose of life) and intending it 2-Understanding our potential powers and manifesting them 3-Accepting our human form including our sex and expressing itThe first dimension is spiritual, the next dimension is mental, emotional and physical, and the third dimension is bodily and sexual. We manifest our talents in a giving movement from the bottom of our soul trough our biological nature onto the subject and object of the outer world. These three dimensions can be drawn as three axes, one saggital axis called purpose or love or me-you, one vertical axis called power or consciousness (light) or heaven-earth, and one horizontal axis called gender or joy or male-female. The three core dimensions of human existence are considered of equal importance for expression of our life purpose, life mission, or core talent. Each of the dimensions is connected to special needs. When these needs are not fulfilled, we suffer and if this suffering becomes unbearable we deny the dimension or a part of is. This is why the dimensions of purpose, power and gender become suppressed from our consciousness.

According to the life mission theory, the essence of man is his purpose of life, which comes into existence at conception. This first purpose is always positive and in support of life. This is not in accordance with the everyday experience that man also engages in evil enterprises born out of destructive intentions. This paper presents a theory about the evil side of man, called the “anti-self” (the shadow), because it mirrors the self and its purpose of life. The core of the anti-self is an evil and destructive intention opposite to the intention behind the life mission. The evil side of man arises when, as the life mission theory proclaims, man is denying his good, basic intention to avoid existential pain. The present theory of the anti-self claims that all the negative decisions accumulated throughout the personal history, sum up to a negative or dark anti-self, as complex, multifaceted, and complete as the self. All the negative decisions taken through personal history build this solid, negative, existential structure. The anti-self, or shadow as Carl Gustav Jung used to call it, is a precise reflection of man's basically good and constructive nature. When mapped, it seems that for most or even for all the many fine talents of man, there is a corresponding evil intention and talent in the person's anti-self. As man is as evil as he is good, he can only realize his good nature and constructive talents by making ethical choices. Ethics therefore seem to be of major importance to every patient or person engaged in the noble project of personal growth. Understanding the nature and structure of the evil side of man seems mandatory to every physician or therapist offering existential therapy to his patient. The theory of anti-self makes it possible to treat patients with destructive behavioral patterns, who want to be good deep in their heart, by helping them let go of their evil intentions. The anti-self also seems to explain the enigma of why human beings often commit suicide. Integrating the shadow often leads to dramatic, subjective experiences of ubiquitous light in an “unpersonal” form, of enlightenment, or of meeting light and consciousness in a personal, universal form, known as G-d.

In 1962, Abraham Maslow published his book Towards a Psychology of Being, and established a theory of quality of life, which still is considered a consistent theory of quality of life. Maslow based his theory for development towards happiness and true being on the concept of human needs. He described his approach as an existentialistic psychology of self-actualization, based on personal growth.When we take more responsibility for our own life, we take more of the good qualities that we have into use, and we become more free, powerful, happy, and healthy. It seems that Maslow's concept of self-actualization can play an important role in modern medicine. As most chronic diseases often do not disappear in spite of the best biomedical treatments, it might be that the real change our patients have for betterment is understanding and living the noble path of personal development. The hidden potential for improving life really lies in helping the patient to acknowledge that his or her lust for life, his or her needs, and his or her wish to contribute, is really deep down in human existence one and the same. But you will only find this hidden meaning of life if you scrutinize your own life and existence closely enough, to come to know your innermost self.
