Within the macrocosm, that is the universe, there are numerous microcosms. For instance, the earth and the many forms of life that live on it.
Breaking this down further, there is the body of a single being and the trillions of cells that live within that body.
And further still, each cell houses its own tiny organelles which are made up of molecules.
And yet still further, each molecule is made up of atoms... and each atom made up of energy.
All of these things do not need to be told what to do, or how to do it, in order to function properly, they just know. This is innate intelligence which could also be called universal intelligence - it is within everything that exists.
Relating this to health can create a newfound understanding and trust in the body's ability to heal itself. Each cell within the body knows what to do - knows what its individual task is, it merely requires the right environment, nourishment and fuel to be able to carry out its job properly. Just as human beings require a nice, healthy environment in order to function at their best, so to do our cells.
So, to the cells within a body, the body is their world. It therefore stands to reason that if everything put into the body is high quality, non-toxic nourishment (including the energy from positive thoughts), those cells are going to be able to function at their optimal level and live happily and healthily in their world. So be kind to your cells, treat them with love and respect, and you'll reap the rewards.
Happy, healthy cells equal happy, healthy people and happy, healthy people equal a healthier, happier world - and likewise in reverse.
So, start feeling the energy that permeates everything that exists, including yourself; tap into it and allow your innate intelligence to guide you and the rest will follow...
