When you think about it, even saying HELLO
to a person has an effect. Your communiction enters his spiritual universe, and in the time of a nanosecond the person will compute your message. That instantaneous computation will either result in his response, or no response, but nonetheless you have transmitted a tiny droplet of your life to him.

ERGO, it is important that our communications to other beings are
positive,helpful messages,and not
destructive, because some people are weak, susceptible, and easily influenced.
We bear a responsibility to humanity
for what we communicate.
