Besides the more one evolves the more one will discover the different grades of people, just like the different keys on the piano. One is lower, another is higher; every person has a different grade of evolution. Also, the higher you evolve the more you will find that you cannot drive everyone with the same whip. You have to speak to everyone differently, in fact in his own language. If you speak a language he does not understand, it will be gibberish to him. If he is less evolved he will abuse you for what you have said. If he is highly evolved and you say something which does not reach his state of evolution it will make you small in his eyes. What is the use? Besides you will always find that inharmony is caused unnecessarily by words. On the other hand, however inharmonious the atmosphere created by other persons may be, if you have the words of wisdom you can dissolve the clouds of inharmony.
