I am a practitioner with my Celestial Eye (Tianmu) open, and I have observed the real scenes of eliminating the evil in other dimensions. I saw that when Dafa practitioners throughout the world sent forth righteous thoughts simultaneously at set times, it became golden and shiny within the three realms, and the evil did not exist within a few minutes. I also saw some Dafa practitioners with their Celestial Eyes open sending forth righteous thoughts either alone or with other practitioners, and they were assisting Teacher with the Fa-rectification at high levels. I saw that "every minute there are countless immense universes that are being swept through by the force of Fa-rectification and at the same time being quickly rectified by the Fa." ("The Effect of Righteous Thoughts") I also saw that sending forth righteous thoughts "has eradicated the evil in many dimensions not yet reached by the Fa-rectification, and has had the effect of eliminating and frightening the evil persons." ("The Effect of Righteous Thoughts") This is really a divine battle, during which the divine power of Buddha Fa is boundless. The magnificent scene is beyond description using human language. Even in this dimension, it has revealed the majesty and greatness of Dafa. For example, in order to freeze the vicious scoundrels, "with righteous thoughts in their minds many disciples are able to use them at will." ("What Are Supernormal Abilities") However, I saw some problems that we cannot ignore. From my understanding, there are at least three aspects that we need to pay attention to:

1. Some practitioners are not thorough in cleaning up their own thoughts, which affects the whole when eliminating the evil. When cleaning up our own cosmic systems, it is especially important to eliminate the warped thoughts. Only by completely opposing everything arranged by the evil old forces, and without any warped thoughts in our minds, can all the righteous forces join together into one body and exert powerful effects in eliminating the evil. Some practitioners did not clean up their thoughts thoroughly, plus there was interference from evil in other dimensions and Fu Yuanshen (Assistant Primordial Spirit). As a result, while sending forth righteous thoughts, some practitioners could not concentrate their minds or maintain the correct hand position, which severely hampered the effects of Supernormal Abilities and Gong Potency. I saw that sending forth righteous thoughts with a clear purpose will result in good effects.
2. An incorrect hand position and mistakes in reciting the verse will negatively affect eliminating the evil. Generally speaking, I understand there are three ways to do it: 1) holding one hand vertically and reciting one verse. 2) Holding one hand vertically and reciting both verses. 3) After cleaning up one's own thoughts with Jieyin (conjoining hands), reciting the verse, "The Fa rectifies the Cosmos, the Evil is completely eliminated" for five minutes while holding one hand vertically; then change to Big Lotus Flower Hand Sign and repeating "The Fa rectifies Heaven and Earth, immediate retribution in this lifetime" for five minutes. I saw that doing it in this last way had good effects in eliminating the evil. The Yuanshen (Primordial Spirits) of those who defamed Teacher, defamed the Fa, or persecuted Dafa practitioners, were sent to hell one by one when practitioners repeated, "The Fa rectifies Heaven and Earth, immediate retribution in this lifetime."
3. Failure to maintain a stable and pure mind, as well as repeating the verse too fast, will negatively affect the result of eliminating the evil. When sending forth righteous thoughts, one should maintain a calm, peaceful, pure, and righteous mind, as well as have the Main Consciousness predominating. This is different from the sitting meditation. The purpose of eliminating the evil is to save all beings with compassion. Compassion is so powerful that it can dissolve any evil. No bad human thoughts should be used. Moreover, many practitioners want to repeat the verses faster, thinking that more times reading the verses will eliminate the evil quicker. What I saw was just the opposite. I saw that reading the verse moderately slower, with each word coming out from deep inside the heart, or each word becoming visible, resulted in Supernormal Abilities and Gong Potency achieving the best effect.

Some fellow practitioners read the verse aloud on certain occasions. Actually, because their minds were not peaceful, this could not have a good result. Plus, it can be difficult for an everyday person to understand if they see this. Anyway, sending forth righteous thoughts are things that a practitioner should do that requires a calm, pure, and stable mind.

Above are my understandings at my level of the boundless Dafa. I hope fellow practitioners can point out compassionately anything that is improper.
