One of the greatest human beings to have walked the face of this planet is Mohandas Karamchand Gandhi, or Mahatma Gandhi. A true man of peace, he always proclaimed that peace and non-violence was the answer to resistance and in the end, his methods proved fruitful. He was also an advocate for living life with no regrets and always preached that people must forgive no matter what had occurred in their life.
The weak can never forgive. Forgiveness is the attribute of the strong. - Mahatma Gandhi
