Gyan Chand has given a good explanation.
As in so many mushairah verses, the first line is both piquant and pointedly incomplete: we are left to wonder that the 'it' might be. After the necessary interval full of approval and repetition, we are allowed to hear the second line-- and even then, not until the very end can we make sense of the verse. Only when we hear likhā hai do we experience the sudden closural effect of full understanding.
This verse is unusual in addressing the Lord with the familiar tum ; almost always Ghalib uses the intimate tū . Since the two words are metrically equivalent, the choice was not constrained by the meter.
Gyan Chand:
The determinists [jibiriyah] believe that the Lord has, from the beginning of eternity, written down everyone's fate/destiny. Ghalib says, 'I am molding what has been written into the form of deeds'. In this verse the mischievousness is that he has put on the Lord the responsibility for all his own sins.
