Mahandas “Mahatma” Gandhi was a wise man who taught his grandson, Dr. Arun Gandhi, some vital life lessons. The younger Gandhi shared some of those lessons Saturday during two lectures titled “Lessons Learned from My Grandfather” at Magness Library. The elder Gandhi used non-violent, civil disobedience to lead his country, India, to independence and inspired a move for non-violence, civil rights and freedom across the world.
