To indicate the continuity of action we use “To keep doing” form of the sentence.
e.g
I keep trying even if I fail.
He kept speaking until all slept.
Do not stop, keep doing

In Marathi sentence formation is:

Like few exceptions the verb “राह” changes to “राहि” before creating its simple past tense.

I keep speaking: मी बोलत राहतो (mI bolat rAhato )
I kept speaking: मी बोलत राहिलो (mI bolat rAhilo)
I will keep speaking: मी बोलत राहीन (mI bolat rAhIn)
You keep speaking: तू बोलत राहतोस (tU bolat rAhatos )
You kept speaking: तू बोलत राहिलास (tU bolat rAhilAs )
You will keep speaking: तू बोलत राहशील (tU bolat rAhashIl )
Keep speaking !! (Imperative statement): बोलत राहा (bolat rAhA)
