Oh wow this painting of Dorje Shugden is so wrathful! I personally prefer the peaceful form of Dorje Shugden but this is nice as well. In fact, I am drawn to all different styles of Dorje Shugden.
It is wonderful how Dorje Shugden, in fact all Buddhas can manifest in different forms to suit different practitioners and our different needs.
Actually all Buddhas are the same. But we personally cannot focus hence the need of different forms of Buddhas to help us accomplish our ultimate goal, Enlightenment. For example, if there is only one Buddha form, when we pray, one minute we will pray for wealth, another minute we will pray for health and another minute we will pray for a different wish. We cannot focus on just one prayer.
But with different forms of Buddhas, people can be more focused. And more likely we will be more sincere.
For example, Dorje Shugden has 4 other different emanations aside from his main form. Each has their specific functions. In general, Shize for healing purposes, Gyenze for wealth, Wangze for overcoming obstacles and Trakze for overcoming black magic.
All Buddhas serves the same purpose. That is to lead us to enlightenment. Many great masters have gain enlightenment by relying on only one Buddha. In a teaching by a Great Master, I was told it is okay to only rely on one Buddha.
My 2 cents worth. =)
