The Laws of the Body are those which restrict the body's freedom: gravity, chemistry, ageing, temperature etc.
The Laws for the Mind are those which others attempt to impose on the mind and limit its freedom: legal penalties (pay your taxes), highway code (drive on the left here, on the right there,) moral prohibitions (don't lie, don't steal, you can eat a sheep's child but not your own). These are sometimes legal prohibitions as well. They involve the body in those areas where it is considered to be under the control of the mind. It is not yet illegal to grow old but you are not allowed to kill yourself (although you are allowed to change your sex).
The Laws of the Spirit are those fundamental laws which are inescapable and affect the very essence of a man. Do good, get good. Do bad, get bad. Do good, be happy, Do bad, suffer (inevitably, sometime).The basic one is that permanent total freedom and happiness is only possible by withdrawing from the limitations of mind and body and remaining in the pure realm of the Centre.
