You may have picked up on the author's not-so-subtle self-congratulation in the use of the phrase: "our great culture".

There is a lot of wonderful material to be absorbed in the ancient texts of India, but the text of that page has a strong Hindu religious nationalist tone (which in Indian languages is called "Hindutva", or "Hindu-ness").

The vast (in time and space), and diverse Indian culture that produced these works was far more tolerant and open to the world's ideas than the apparent mindset of the individual(s) who created this site.

So try to enjoy the actual linked texts, but observe, and then ignore the religious nationalism that seems to have inspired the site.
