Dependent Throughout

To take some clay to form,
After conceiving a form in my head.
Nothing will happen until I begin to
  take action.

I am only one of many other causes
  and conditions.
The combination of clay and water.
Beyond this, the molecules, atoms,
  and other particles must come together.
Which themselves are dependent on
  innumerous factors.

There is also, the circumstances to my
  decision what to make.
The conditions of my actions to give
  the clay shape.
All these factors are clear that it cannot
  come into being independently.
It is dependent throughout the creation.
