Is the language of Vedic era Sanskrit, different from the Classical era Sanskrit?
I have heard, read and listened at almost all the forums regarding this prevalence of difference.
Some of the people say that Sanskrit in the puranas is different from the Sanskrit in the Vedas.
But some of my other close people, say that there isn't much or no difference at all.
Some say that only the Vedic Sanskrit should be the original "Language of the Gods" and the Classical Sanskrit is man-made.
I find these kind of logic, personally a nonsense. But, I'm not a authority. I'm looking for direct answers from the higher defined authorities.
So please answer,
Does any scriptures or important guru people in the Hindu culture or community make such observations regarding the difference or sameness of the colonial defined categories of Vedic and Classical Sanskrit language?
What does the Hindu scholarly canon say on this problems?
