What is the ethical lesson that thoreau learned in prison?

Henry David Thoreau was the author of the essay Â"Philosophy of Civil DisobedienceÂ" His essay on civil disobedience is based on his own life, Henry David Thoreau did not want to pay his taxes since he was opposed to them radically used to finance the war. The eternal religion, Hinduism, inspires a spiritual leader of Christian civilization, Thoreau. Although Thoreau was transcendental, we have included him in this study on Christianity, not because of his religion, but because of his belonging to Christian civilization and for being a true spiritual leader based on nonviolence.
