We keep things dear to our hearts. We grow deep affections for them. We put great value on them and call them sacred. We fear losing them and suffer. We defend them by causing suffering for others, calling it honor. We make an image in our mind and try to change the world to match that image. We are certain of the reality we perceive and insist on the validity of our opinion based on that reality.
Others see it differently and conclude otherwise when conflict of opinions arise from different perceptions of reality.
Our suffering and pain is real. We go through them every day. We suffer from thoughts of loss from the past and future. It is the time we created in our minds that connects us to the past and future, but our suffering happens at this moment, right now. It ruins our present moment, the only reality.
