Within our individuated 'selves' and as a whole we manifest an incredible Complexity. The microcosm of the individuated being is a whole example of the massive Complexity of the macrocosmic whole. Through a careful study of the equipment with which we are endowed we can come to appreciate that of which we are a part.
As the bodies (gross and subtle) of which we can become aware, integrate and become a cohesive whole, we gain understandings of how the larger organism in which we are the 'cells' can reach for integration and wholeness.
There are subtle analogies which the mind can create to help us reach this level of comprehension.
