"The oil of the Torah needs a wick to hold the flame of light"

It cannot burn of itself.

Something has to transfer the oil in small, controllable quantities.

Otherwise, there is a conflagration.

And it is the body of man that constitutes such a wick.

The ignited flame is the mitzvah, giving off a spiritual light.

The body functions as a useful device.

It helps to manipulate the immense things of the world so that there can be ‘light’ without an explosion.

Of course, the body also causes a lot of trouble for the soul.
