Spiritual practitioners mustn't have ego. With ego, we can not be liberated from sufferings of three evil. Where does ego come from? How to eliminate the coarse ego and the subtle ego that is difficult to identify? Supreme Master Ching Hai points out that we can say ego is a kind of personality which comes from habits. Each time we are born as humans or animals, or as heavens or hells, animals or evil spirits, we all have some habits. We collect so many bad behaviors when we reincarnate life after life that they form a record, just like the recording cassette, which can be played once the button is pressed, and which will come out automatically once chances and situation arise. If we want to keep the karma from growing deeper, we have to avoid our own habits, not letting it emerge again, because when it emerges, it will become deeper.

That’s why we need to practice Guan Yin Method in order to cleanse those bad habits from inside. Guan Yin Method is not a language, it is a vibration, or electricity or magic power, which can cleanse all our random and wrong thoughts. Even though Master tells you to recite the Buddha names and do light meditation, but if you do not meditate on the sound, it will not do! Because reciting holy names and light meditation is also adding another thing in to use the benevolent Buddha names to control our random thoughts, yet it doesn’t cleanse those thoughts with the Buddha names. We add in tens of thousands of times of the Buddha’s names every day, so that they are powerful enough to control the random thoughts. Then we should use Guan Yin to cleanse everything, including the Buddha names. That’s why Master said, anyone, if he doesn't do Guan Yin every day, can't say he is fully enlightened or has become Buddha. He would be lying.
