What are four types? It could be also people; it could be also invisible beings; it could be also animals, pets. So now, I classify it all in four types of beings. Because we are all beings. The first type is very lucky for us if we have; they're called "Friends." "Friends" doesn't mean the social circle that you are in only; it could be your family members. So, friend is good for you. You will notice that they are very helpful to you, very coordinated with you. When you're with them, it's smooth sailing. And in our group, we have sixty-plus percent are good, truly, sincerely want to go Home and to practice goodness and to hear the Truth and try to implement the Truth in their lives. And the other thirty-plus percent are not so. And just like other Masters, when They came to our planet, They generously gave initiation and just giving everyone a chance to know this method and then to be able to practice. But not everyone took it seriously. The same with Shakyamuni Buddha. Even His cousin always tried to harm Him.
