Advising people to take this attitude or that are a waste of time. Those who see or/and are aware realise also that it is none of their business to goad and advise others. Our job at best can be to answer questions by the light of our knowledge but in no way can anyone be dogmatic about it. Let us all be first aware of - Do we know? What do we know? How do we know that we know? To me it is the part where we first accept that there is room for change for the better in us. Then we observe ourselves. And finally we try to bring in the change in ourselves with our will with sincerity and objectivity.
When discussing illness and cures, let us not forget the "generator" deep within us. Depending on the level of our conscious development of our compassionate, grateful and discerning «SELF», the quality of energies bubbling from within us can make or mar our lives. The quality and intensity of our Desires, Well-wishing and Aspirations all get energies from our Inner Being and seek for "Realisation" into the outwardly material world. Prayers or thoughts and feelings create ripples that have "real" and penetrating effects on us and the people, things around them. The material, physical bodies are also affected. Our own lives are affected.
