Lama Ole’s answer:
It is important to put your energy into solving your problems instead of thinking about them. This also applies to sicknesses—they don’t pass more quickly if you think of them constantly.
In the moment a situation gets difficult or you become sick, it is good to put all your energy into the goal—that is, into the solution of the problem or into your recovery. Your mind and thoughts shouldn’t dwell on the problems. Then you will get through it in the best way, and the karma dissolves.
Otherwise, it is simply stupid not to fight something that has to be fought! But if the karma still doesn’t dissolve, then observe what is there. In fact, in the moment depression, sickness, or other difficulties appear, the original cause is gone. Then it is only a question of time until the negative karma has been removed—until the effect is gone. And there one should do whatever is possible with one’s body, speech, and mind! Non-Buddhists try to avoid difficulties wherever they can and to constantly experience something beautiful instead. This is why the many ups and downs in life appear.
All “trips” you experience are like images in the mirror. Behind everything that happens—behind every grimace, every devil—is a clear mirror that doesn’t change. This is your buddha nature! So try to act as normally and meaningfully as possible while you work through the difficulties on your way. Then everything you do will have long-term effects and great strength. Work with this attitude: “I am a buddha who just hasn’t recognized it yet.”
