A white tiger is white with black stripes. More appropriate in this case is the white part, as it applies to the five element color associated with the lungs. Seeing the 'light' aspect to the white is good to. The radiance.. In SFQ white light/energy is put into the lungs, or a person can see their lungs as bright white. Remember, that when you use an image like this tiger, it becomes a spiritual-energy helper, so internal respect and thanks is called for. The image helps you, has presence, and therefore is treated with respect, just like the master's energy, or for SFQ practioners who have done level 4, a rainbow is summoned. These things are done, after merging with the universe, and utilizing the master's energy. As I said , the tiger idea comes from five element/ Taoist method. It isn't superior to just using white, but there is a nice animation to it, or strong image, that a younger person might connect too. The lungs also relate to the positive emotions of righteousness and courage, which a tiger image nicely supports. The 'white' part is important, and underlying this image. -g
