Doubt: State Action vs Instrument of the State

Yaar samajh nahi aaya, please help. Meri DU LLB Entrance ki tayaari mein yeh concept to bahut important hai. Main kahaan se shuru karta hoon... State Action aur Instrument of the State dono hi kya hain? Dono hi State ki kriya ke liye use kiya jata hai. Lekin difference kya hai? Main kahaan tak pahunchta hoon... Instrument of the State ka matlab hai ki koi state ka karmanaya, jaisa ki aadhaarak kanoon, hai. Lekin State Action ka matlab hai... hmm... kuch aur hai?

Please koi example ya case law share kare jo is difference ko clear kare. Main to samajh nahi pa raha hoon.
