Everything that we write matters. Everything that comes out of our mouth matters. Important communications require calm and insightful reflection afterwards. Wisdom and Liberation of the voice support each other. Clear communication with another (spoken or written) expresses itself freely from the extremes of positivity and negativity.
The middle way shows itself in exploration of conditions and the factors which contribute to understanding what arises. Insights into the process supports wisdom. Positivity shows itself in the exaggerations of perceptions of anyone or anything with regard to past, present and future. Negativity shows itself in fear and blame.
The Dharma points to wise application of speech and wise application of noble silence. How do we communicate with the friendly, strangers and the unfriendly? What are the lessons we have to learn? Are we dependent on consequences on what others say or what we say? Liberation includes freedom from dependency on consequences for peace of mind.
