Hindus believe in each individual as a soul, a divine being who is inherently good. We all have a threefold nature: instinctive, intellectual, intuitive. Develop the intuitive/spiritual/soul nature with compassion, devotion, penance. Use the intellect to help subdue the instinctive mind. Guilt is not a part of Hinduism. There is no eternal hell. You have a continuity of consciousness when you transition to the inner worlds. There is no devil, but there are mischievous "asuras."
