To have faith is to trust yourself to the water. When you swim you don't grab hold of the water, because if you do you will sink and drown. Instead you relax, and float.
All that we are is the result of what we have thought. If people speak or act with evil thoughts, pain follows them. If people speak or act with pure thoughts, happiness follows them, like a shadow that never leaves them.
When young we have a vivid sense of basic values like trust and warm-heartedness, which we tend to neglect in today's competitive world as we grow up, yet from birth we all have a need for affection. The emotions we experience today have not changed much over the last few thousand years, but the interest increasing numbers of people are showing in their inner world and how their emotions work is a sign of maturity.
