My opinion in this matter is slightly different than that of Suresh.
Hinduism in general and Brahminism in particular encourage plurality of thought as long as the lines of thinking are intellectually sound and amenable to debate, and that debate itself remains parliamentary.
Since knowledge is one of the corner pillars of intellect, I believe it helps if one has a first hand knowledge of what is written in the scriptures. As most of our scriptures were written in Sanskrit, some knowledge of Sanskrit does help in having a direct understanding of them.
For example, we have diverse philosophies to choose from, such as Sankhya, Yoga, Mimamsa, Nyaya, Vaiseshika and Vedanta (which is nearly Buddhist according to some), and even the Sunya Vaada of Charvaka. One can even have one's own line of philosophy if he /she is intellectually capable of propounding one.
If we instead blindly go by the interpretations given by others to these texts, sooner or later we might become like those Taliban in Madrassas whose Mulla taught them that it rains when Allah uses the loo!
