to identify the sargun was the part of the plan of nirgun,,,,,,from nirgun mode, that is no-2,source heart..the command was set in to move the wrist,,,thats 0 micro sec....the sahasara is incited....at 350 micro sec the command reaches agnasargun....and finally the wrist moves at 550 micro sec.....so the entire action was initiated in nirgun mode and completed in sargun mode ater 550 micro sec...so what exactly jiva did was carried forward the command....as a courier...postman...who under the wildest speck of imaginations cant be the writer of letter,,,,
