Wow, this is impressive, having Dorje Shugden on the billboards all around the world!
In this degeneration age, we need Dorje Shugden badly as he is swift to come to help when we call upon him. Since he is the emanation of Manjushri, he is able to give us wisdom and guide us to the path to enlightenment. By seeing his holy image, we have already planted a Dharma seed in our mind. Thus, having the potentiality of gaining enlightenment.
Imagine, if there is a movie about him, gaining popularity internationally, being shown in movie festivals in Nice, Berlin, Hong Kong, Taiwan, etc. Lots of people will start to be curious about him and more people will start to practice him. I knew HHDL from the movie 'Seven Years in Tibet', it was this movie that made me curious about HHDL and started to google about him. This was when my interest in Buddhism, especially Tibetan Buddhism started to grow. I am sure one of these days, these wishes will come true.
