Abstract: Jainism is one of the heterodox schools of Indian philosophy. It is more known as Jaina Dharma by tradition. The followers of this philosophy are called Jaina. This word is derived from the Sanskrit word Jina which means victor. In life, one gets victory when he can come over the bondage of Karma and this happens only when he leads a spiritual life. This philosophy is well known and followed for its treatment towards a peaceful life. Non-violence in its deepest form is the key factor of this branch. Over the ages, it has inspired millions and billions of people all over the world. Mahatma Gandhi, the Father of Indian nation was greatly influenced and inspired by Jainism. Gandhi who lead India in its freedom movement applies the teachings of Jaina philosophy quite practically. The adaption of the core concepts of Jainism by Gandhi can be seen throughout his life. How a philosophy can inspire a man in particular and a nation or the greater world in general is the subject matter of the proposed paper entitled JAINISM : PHILOSOPHY THAT INSPIRED MAHATMA GANDHI.
