Purusha sUkhtam is presented in a specific sequence, starting from macro cosmic creation and Purusha's omnipresence in everything to how this manifestation must be sustained by yajnas as root of Dharma so that Glory is attained.
A deeper analysis of the Suktham would reveal some valuable clues to understand what Creation means. Creation is not simply about the formation and expansion of the material Universe that we see. The current thinking on Creation and material Universe is that matter expands and consciousness enters into that giving life to that. It is not so. The basal factor that exists is Consciousness which is called Purusha. It springs up into different forms with specific faculties attached to them.
The best way to understand is to compare this with formation of a child.
How does the child come into being?
Is it the physical body or the life (consciousness) that comes first?
What gives the shape and form and faculties to the child in the making (in the womb)?
Is it the consciousness (life or athman or soul) that gives shape to the body or the body gets a shape of its own and the soul enters it?
If we ask these questions, we will come to a realisation that it is the soul that gives the shape to the child. Even though the formation of organs is programmed and is almost mechanical in development, how a child gets the organs and its functions is determined by the soul and not by the physical components themselves. To explain this better, let us imagine that a couple get a number of children. Though the basic components come from the same parents, no two children are the same. They differ in appearance and in faculties. The physical features are not the same. The mental capabilities also are not the same for all the children of the same parents. One of them may have the eye, but may be born blind. One of them
