Saying things you shouldn’t
say or speaking much more than is necessary brings a lot of agitation to the
mind. The other extreme, complete silence, or not speaking up when it is useful
or necessary, is also problematic. Applying right speech is difficult in the
beginning; it takes practice. But if you practice every time you talk to
someone, the mind will learn how to be aware, to understand what it should or
should not say, and to know when it is necessary to talk.
