Spiritual principles CAN lead to material success. The premise is this: If we get in our own way and block our own success due to unconscious, self-sabotaging behaviors, then when we get out of our own way by stopping our self sabotaging behaviors, the roadblocks to our success will disappear and we will manifest the goals that we desire. The way we end self-sabotaging behaviors is to end the guilt, shame and self-loathing deeply embedded in our unconscious mind which is causing the self sabotage. The way we do this is to forgive and love ourselves. The way we forgive and love ourselves is to forgive and love others, and be of service to others unconditionally without need for acknowledgement or reward.
