Every adversity both teaches us some truth of Dharma and gives us some opportunity to train our mind. In this way, our suffering becomes a cause of our enlightenment.
What we lack is (1) a stronger wish to attain enlightenment than to enjoy a pleasant life, and (2) the wisdom necessary to know how the adversity we are facing is exactly perfect for our spiritual training.
If we wish to enjoy samsara more than to accomplish spiritual goals, knowing how to transform our suffering into the path won’t work to help us maintain a peaceful mind in the face of life’s difficulties. We will think, “oh, that’s nice, but I don’t care. I just want my suffering to stop and the external thing is the cause of my suffering or cause of my happiness.” But when we want to accomplish spiritual goals more, it all works. We become willing to accept difficulties – meaning we can keep our inner peace in the face of them – because we know they are moving us closer to our much more important spiritual goals. Fundamentally, we understand that whether we are happy or not depends upon our mind, so the only way to be happy is to change our mind – our external situation is almost irrelevant.
Dorje Shugden can help with both of these things we lack. For the first, he is the protector of the Kadam Dharma or Kadam Lamrim. The actual Dharma only exists within our mind. He protects the flourishing of the Dharma within our mind. The quintessential butter that comes from churning the milk of Dharma is bodhichitta, the wish to attain enlightenment. Just as all rivers eventually flow into the ocean, all Dharmas flow into the mind of bodhichitta. The Lamrim principally functions to change what we want from worldly happiness to spiritual goals, up to the wish to attain enlightenment.
For the second, Dorje Shugden is a wisdom Buddha, an emanation of Manjushri. His blessings are particularly powerful to help us understand how what we are facing in life is perfect for our next step in our spiritual journey. All we need is faith in him and a pure spiritual motivation. We then make requests that he arrange what is best and that he bless our mind to see how what is happening is best for us. When we receive these blessings, we then see and know. This enables us to accept our situation and get to work on transforming our adversity into the path.
Just as Dorje Shugden can do all this for us, he can also do all this for those we love. It may not be as quick or as obvious how this is happening, but since he, those we love, and ourself are all empty, it is definite it is happening. We gradually karmically reconstruct our empty world.
Because the methods we have are perfectly reliable, all we need is the perseverance necessary to never give up and both we and all those we love will get there in the end. This is why it is the Joyful Path. We know the final outcome is assured.
