religious faith to "feel" powerful when facing disease does not solve the issue of pain, because the "titles of faith are not mere words to cover our deficiencies and weaknesses. They express duties of improvement that we cannot escape without further obligations. In our circles of work, thus, it not enough simply believe and convince. " (2) There are specialists who support this argument, considering that the look optimistic about disease, and firm thought in healing are powerful mechanisms that can help patients cope better with the treatment of cancer and resume a normal life. As an example we have what happens to the Vice-President of Brazil - Jose Alencar. Currently, more and more people are surviving cancer and this survival, are related, without doubt, to emotions and thoughts, rich content of vibration between the patient and the Creator. Many patients, before the diagnosis of disease, transform pain into hope, and awaken in them the will to fight for a better life. Others, however, give up, assuming they are under a death sentence. Regarding the process of human thought, the academic science, which is materialist by excellence, purpose that the phenomenon is purely physiological, due to incessant activity neuronal. But the Spiritists know that the mental matter is the creation of energy that externalises from the spirit and spreads by a flow of particles and waves, as any other form of propagation of energy in the universe. As in physical field, thought, in vary degrees of excitement, generates waves of length and frequency correspondents to the content of the creator impulse of will or desired objective. The reflections of thoughts returns to ourselves Thinking is a process of projection of mental matter and this matter "is the subtle instrument of will, working in formation of physical matter, generating the motives of pleasure or grief, joy or pain, optimism or despair, which do not reduce, effectively, abstractions, because they represent eddies of force where soul creates its own states of inductive mind, drawing to itself the players [for now imponderables] of light or shadow, victory or defeat, happiness or misfortune. " (3) In this respect, thought is not intangible anymore to substantiate in the condition of matter in motion. The reflections of negative feelings and thoughts that we feed ourselves come back to us, after being transformed in mental waves, confusing our organics functions. So, thought, as a subtle form of energy, acting in a kind of wave, with a speed much higher than light, when passing by places and creatures, situations and things, affects integrally our health. "When we surrender ourselves to imbalance or disruption or when we establish perturbation against us (...), we reflect in the psychosomatics tissues certain fields of rupture in cells harmony, creating morbid predisposition for this or that disease, and therefore the entire area affected becomes susceptible to microbial invasion. " (4) By thoughts of fear, exacerbated anxiety, disappointment, we slave ourselves in trunks of painful punishment, sentencing us, sometimes, to years of pilgrimage in the tracks of spiritual uneasiness. And to shorten the torment that plagues
