The final stripe in the sequence shown is a white stripe representing the warrior dignity of Meekness. The dawning of the Great Eastern Sun unfolds with the experience of joining sadness and joy. According to the Shambhala principles you should feel that way with everything you do. Whether you have a good time or a bad time, you should feel sad and delighted at once. That is how to be a real decent human being, and it is also connected with the Buddhist principle of longing or devotion.
Longing is the hunger for sacredness.
When you begin to feel you're too much in the secular world, you long for the sacred world. Therefore you feel sad, and you open yourself up that way. When you feel so sad and tender, that also brings ideas for how to uplift the rest of the world. From the experience of the simultaneity of sadness and joy, we radiate peaceful confidence, which is the first quality of the Great Eastern Sun. Second is illuminating the way of discipline, which is realizing what to accept and what to reject.
