Tough question, but I'd have to say Yehoshua of Nazareth. He lived a life of spirituality, placing importance on love, responsibility and humility.
I was born into an interesting family. My mother's father was a Southern Baptist minister, but I didn't like his brand of fear-motivated churchiness. My father inspired me by his humble search for spiritual answers in numerous philosophies, from the Bhagavad Gita to Edgar Cayce.
I found great inspiration from the works of L. Ron Hubbard, and grew spiritually by leaps and bounds by unburdening the hidden sources of spiritual torment.
I found great inspiration from the teachings of Gautama Siddhartha Buddha. I learned from Rinpoche Gyaltsen and other Tibetan Buddhist monks the beauty of generosity, wisdom and compassion and the power of the paramita of these.
And I returned to Christianity, understanding far more than I could ever have if I had followed someone else's dogma "religiously."
