Dhammapada, 1:1-2

All experience is preceded by mind,

Led by mind,

Made by mind.

Speak or act with a corrupted mind,

And suffering follows

As the wagon wheel follows the hoof of the ox.

All experience is preceded by mind,

Led my mind,

Made by mind

Speak or act with a peaceful mind,

And happiness follows

Like a never-departing shadow.

Buddha, Dhamapada  1:1-2

The first verses of the Dhammapada remind us to guide our thinking, because our thoughts inform our experience.  Everything that we go through, every event, we interpret with our minds.  But experience also has a way of shaping the way we interpret our experiences.  The families into which we were born, the people and cultures that shaped us, inform our minds, the ways we see the world.  So, for example, a child who is mistreated from the moment she is born,who is told that she is worthless and stupid and incompetent, nothing more than a thing to be used by others, is likely to grow up with a false understanding of herself.  She will not know her true nature as a being of light and beauty, deserving of all love.  She will have a corrupted mind, and suffering will follow her.

The wonderful knowledge that the Buddha offers to us here is this: no matter what has happened to us, no matter how corrupted our ways of understanding the world have been, each one of us has the freedom and the power to learn, through practice, to step aside, as it were, from the false, corrupt thoughts that have been imbued in us, and to have a “peaceful mind.” This is the only path to lasting happiness.
