G:

Mohandas K. Gandhi:

• A man who was completely innocent, offered himself as a sacrifice
  for the good of others, including his enemies, and became the
  ransom of the world. It was a perfect act.
  (The man he was referring to was Jesus Christ).
• Prayer is not an old woman's idle amusement.
  Properly understood and applied, it is the most potent instrument of action.
