When the breath is balanced, it is like an expansive lake with very still water.
Left alone, the lake reflects the things around it very beautifully.
But if we disturb the lake by throwing a rock into it, a clear and beautiful image can no longer form.
Watching our breath, we can see whether it is still and balanced.
If it is out of balance, then by watching with care we can discover what disturbs us.
