In general, all methods for attaining buddhahood rely on sentient beings. Therefore, to the individual who wishes to awaken, sentient beings are as worthy of gratitude as buddhas. Do not be angry, not even at a dog or an insect. Strive to give whatever actual help you can. If you cannot help, then think and say: “May this sentient being (or troublemaker) quickly be rid of pain and enjoy happiness. May he come to attain buddhahood.”
