From a non-dual perspective, physics, chemistry, biology, psychology are simply different points of view on one and the same Oneness. Philosophically synergistic conclusions ensue: sensation (as in touch, sight, hearing) is just an elaboration of chemical valence. If viewed deeper - ie less dualistically - we can think of physical forces - such as force of gravity or magnetism - as vectors of wellbeing. You kick soccer ball up into the sky and comes back down. Why? Because it... wants to. Why does it want to? Because, made of Earth, it wants to return to Earth. Is it this a force of gravity or a force of attraction/attachment? Perhaps, it's nothing more than a linguistic distinction - a distinction that is an artifact of our particularizing/partitioning point-of-view.
