Namaste all
The terms faith, optimism, hope and positive attitude have all been used here in an interchangeable manner. To me, I think of faith when I believe that the person that I love is worthy of it no matter what their actions are. Unconditional love is based on faith. But this does not mean that you become a doormat to anybody.
I think of faith when I do reiki practice believing that a system of healing exists in this world. I have faith that there are things that happen beyond our understanding of the five senses.
