However, I can't help but notice that each of the three faiths I mentioned often speak more of their 'prophet' than they do of their god himself...
That might come from a natural inclination to revere more than just one being. Polytheism, as we know, was the rule before imperial monotheism.
If I ponder on the Trimurti and the function of each of the three, it seems creation alone is... pointless. If I create a cat, but don't sustain it, what good is it? Brahma can create, but if Vishnu does not preserve, its in vain. But then what of Shiva's function? If Brahma creates and then Vishnu preserves... it stagnates. And that simply isn't how the powers of the universe work. This is where Shiva comes in to repurpose what in no longer serving. Without this mercy, the cycle would end.
This is such a brilliant way to look at the Trimurti!
Perhaps its easier to relate to being preserved or let go. If my mother gave birth to me, but abandoned me for another to care for, I would likely reserve for the person who saw to my health during my formative years.
Yes. The formative years, of course, are longer than the mere nine months of being carried and then born.
