Well, not this - this is speculative PIE, not sanskrit.
Not that lithuanian and sanskrit are siblings either, but they do seem to be closer. (From what I gather, it's a case of lithuanian being very conservative, while sanskrit is just plain old).
On a related note, just how impenetrable is latin to someone that speaks italian? Is it like old norse to me, where I can sort of guess at sentences but a bunch of the words are derived so far I only see the connection after looking at a translation?
