Most people here do not seem to know Hinduism beyond rituals. Do any of you guys out there understand the old form of Sanskrit language ?

I don't either. I have just begun to try to understand some of the earliest Hindu Vedas. To be frank it's hard to understand Vedas beyond literal interpretations from Sanskrit language to more accessible languages.

Understanding the old form of Sanskrit is hard enough, challenges of interpreting them as literal meanings as opposed to interpreting them as metaphors, similes, adages etc are even harder. Probably because of lack of translations of these Sanskrit texts into local languages Hinduism is much less likely to be easily understood.

Adherents of Buddhism by contrast did something ingenious (at least ingenious for ancient India) by translating texts from Sanskrit (and its older sister language Pali) into many languages foreign to ancient India. You can find Buddhist text in Greek language from the time of the great emperor of India Emperor Ashoka.

प्रज्ञा पारमिता हृदय सूत्र (The Heart Sutra) recited in Sanskrit language and the same प्रज्ञा पारमिता हृदय सूत्र recited in Japanese language (bottom video).
