The Path to Awakening

"When beings and the world are filled with evil, convert adversities into the path of awakening."

Due to their self-clinging and negative actions, living beings (and therefore the world) are filled with evil.

You should call to mind that suffering is the maturing and passing of bad karma. Like everything else, negative karma is also impermanent--it will eventually run itself out. Since the results of your own actions always ripen on you, it is better to deal with them now as best you can and be done with them.

The reason why the lojong methods are so special is that they show you how to take advantage of your negative karma. You can deploy the methods to actually transform every undesirable circumstance into an opportunity to practice the dharma.

How does this work? Your suffering connects you to the suffering of sentient beings by making you understand that suffering is universal. As you suffer, you can resolve to absorb all suffering. Your motivation, however, must be genuine. When it is, adverse conditions essentially become a means for you to accumulate good karma, or positive merit. Think: 'I am suffering. Through my suffering, may I absorb all the suffering of others and relieve them.' This wish, grounded in relative bodhicitta, purifies your karma and, in effect, reduces your resistance to your own suffering.
