Centering is the path, not the goal. Centering is the method, not the result. Samadhi is not called centering; centering is the technique to samadhi. Of course, they look contradictory because when one realizes, becomes enlightened, there is no center left.
For example, an iceberg is floating in the sea. The iceberg has a center of its own. It has a separate individuality; it is separate from the ocean. Deep down it is not separate, because it is nothing but water at a particular degree of temperature. The difference between the ocean water and the iceberg is not in their nature - naturally, they are the same. The difference is only of temperature.
And then the sun rises, and the atmosphere becomes hot, and the iceberg begins to melt. Then there is no iceberg: it has melted. Now you cannot find it because there is no individuality, no center in it. It has become one with the ocean.
