Sanskrit - 000001

I was trying to make some long sentences. Not sure of their correctness though - although they seem about right. There is no way to verify because:
a.  not many people know/ speak Sanskrit
b.  those who do will generally nitpick minor grammatical points and drive you crazy

I use http://www.learnsanskrit.org/tools/sanscript tool for converting ITRANS encoded text to Devnagari font. For vocabulary check I use http://spokensanskrit.org/
