Shutri means the spoken word. Or "what is heard". In a broader perspective of Hindu mythology, Shutri means all that we perceive. They say that the knowledge of music is prebuilt in the strings of Violin but the comprehensible music sounds only when the strings vibrate in a specific accord. In Sanskrit, Shruti that later got deformed into Shutri in Hindi are the bundles of wisdom to invoke Smriti - the prebuilt knowledge. At the end of last session of Gita - Arjuna thanked Krishna . He said

Nashto Mohah Smritir Labdhah ;

I am now free from delusions , Now I am with my internal knowledge Smriti.

In essence, Smriti is the incidence of knowledge in Atma. Shruti is a narrative, carefully crafted to invoke the Smriti.
