Atisha once told his chief disciple Dromtonpa Gyalwe Jungne, “My master told me that when a thought arises, observe and realize its nature. While doing this, you will meet the true Self of the Buddha (dharmakaya).” Dromtonpa asked, “What should be done when a thought arises again?” Atisha replied, “When the thought arises the second time, go realize the nature of the thought again. You will meet the enlightened truth body of the Buddha for the second time and do likewise the third, the fourth time and so forth. If there are one hundred various thoughts in a day, greedy or hateful ones among others, you will meet dharmakaya one hundred times in a day this way.” What is dharmakaya? It is simply the nature of our mind, also called Buddha nature which is the same essential nature that practitioners of Chan Buddhism seek to realize.
