Basic beliefs are formed from the first days of a child’s life, although some areas of psychology claim that even earlier. How safe a child will perceive the world depends on the significant adults present in his life, namely their sensitivity and responsiveness to his basic needs and the completeness of their satisfaction. A. Beck in his works suggests that a person evaluates his life through the prism of basic beliefs, and in the process of this assessment, what corresponds to accumulated experience is accepted and what does not correspond to this experience is rejected. Since most adults still cope with their role, the basic beliefs formed at birth help the child to trust the world at large and feel safe, and in adulthood these beliefs will help to feel stability and invulnerability (1). S. Taylor, in 1983, co-authored with John Brown, introduced the “Implicit Concept of the World and the Self.” According to this concept, people who are well adjusted in life are more likely to expect positive events to occur than negative ones. Beliefs that present in such people, she called “positive illusions.” An example of such a belief could be: “Good things happen to people more often, and bad things happen only to those who do not live correctly. If I do everything well, then it cannot happen to me. nothing bad will happen.” Living as if you are immortal means living according to Taylor’s illusion. Adaptation after a difficult life event affects the stability and justice of a person’s beliefs about “the benevolence and hostility of the world around him, its fairness, as well as the value and significance of his own.” Self." Therefore, according to her theory, to successfully overcome traumatic experiences, it is necessary to find new meanings in life, rebuild one's life taking into account new circumstances, restore a sense of control over life, and also find new supports in oneself by increasing self-esteem and self-esteem (3). The theory, developed by Ronnie Janoff-Bulman in 1992, concerns the impact of negative events on three inherent assumptions: the general benevolence of the world, the meaningfulness of the world, and self-esteem. This concept is similar in many ways to Taylor's theory. Janoff-Bulman suggests that there are difficult life circumstances, which can be called traumatic, that destroy these worldview values. In the event of a traumatic event (such as the loss of a loved one), each of these assumptions is challenged and a loss of the assumed world may occur (Kaufmann, 2002). Healing from such a loss can be especially painful and very protracted, since the solution to healing for the bereaved must be the creation of new assumptions. If we return to Aaron Beck, he also drew attention to the deformation of a person’s ideas about himself, the world around him and the future in people who have suffered mental trauma. Janoff-Bulman's path to recovery from a traumatic event is very similar to Taylor's. Working with negative thinking, strengthening self-sufficiency, discovering and creating new internal and external supports and working on creating new meanings will help change this picture and create a new foundation for later life. It is necessary to understand conscious and unconscious motives of behavior, the main ones are meaning-forming ones, which are leading in a person’s life (2). Viktor Frankl (1962), in his seminal work Man's Search for Meaning, argued that “people are driven by a psychological need to find or create a sense of meaning and purpose in their lives, and that this can facilitate their ability to face and overcome even the worst from experiences” (4). It is important to find new meanings, discover resources and be in contact with the outside world on the path to overcoming grief. No matter what therapy model.
