We have to be something before we can talk to other people. If not, it's empty talk, nobody will listen. Even though they might listen, but inside they feel this is not true.
Most people can only criticize and they cannot contribute. That is where they go wrong. I make criticism as well as contributions. Only in this way is a comment useful! What is the use of criticism only? Anyone can make one. Using your month to speak is the simplest thing to do.
Whatever we say, our brains record. With all the "It's lousy, no good, too expensive!", no fresh information can fit in. Continuing to be negative, we get lower and lower. The more negative we are, the worse off we become. We recite our own negative mantra to curse ourselves. That is why it is bothersome to be your teacher. I am affected and collect a lot of karma, because everyday you keep using the negative power and qualities for me to hear or see.
For example, when I ask on the phone if someone is in, you could say, "Oh! Master, she is not here. Can I ask her to call You back later? Is there anything I can do for You or for her?" Is that not better than simply saying, "She's not here!" (stop dead) or "She went to the toilet." (stop dead here too)?
