Sanjaya Uvacha –
Thus saying to Krishna, Arjuna, who is about to curb his ignorance, said I am not going to fight and became silent.
Sanjaya, through his divya drushti is narrating the battlefield to Dhritarashtra. Because Sanjaya is narrating this, he might be using the words hrishikesha(who is the master of senses) and gudakesha(the master of curbing ignorance), hinting what might unfold later.
Arjuna is overwhelmed with grief, he is overcome by his feelings for his near and dear ones and is not able to fight, even though he is parantapah(chastiser of enemies). And Sri Krishna who is the master of senses is about to guide him.
