What is Mahatma Gandhi's concept of Truth (Satya) and Non-Violence (Ahimsa)?

Gandhi's Philosophy of Truth & Non-Violence:

• Truth (Satya): Supreme reality and ultimate goal; Gandhi famously asserted that 'Truth is God'.
• Non-Violence (Ahimsa): Means to achieve Truth; active moral force involving absence of ill-will in thought, word, and action.
• Satyagraha: Soul-force or truth-force; peaceful resistance against injustice through self-suffering and moral persuasion.
