The poem is asking us to surrender. Surrender to what? The What is whatever comes in the consciousness. It also mentions that it is a sublime game of chess. With God.

It talks of the two stages. One is the oridinary human being who does not surrender and is waiting for the thousand moves. These thousand moves will make him suffer so much that finally he will be ready for surrender.

So the poem is describing the need to surrender. However the Saint doesnt seem to be the ‘Realised one’. He is still a seeker. Else he would not say I surrender. Or he would not think that this is a game of chess with God. For him the God is still the Other. And God is still an opponent.

The poem doesnt describe the third state. The one where one does not even surrender. Because there is no other. So whom to surrender.
