I had written about Purusha Suktam and my interpretation of it in this blog, here.
I had not explained the meanings of some of the verses in detail (as I see it), as my aim was there to bring out the meanings as it appears in verses in that article. Here I would fill the gap.
An assumption that we all make is to assign the word Purusha to a Supreme Being, a person or some Being intuitively. That need not be right.
