First Nanak beheads the chicken, then pull off the wings. After the bird is naked what Nanak does is slit open her stomach right there between her legs. Then by using your both his hands the Baba pierces the stomach with his fingers and force open her belly. Now Nanak can see everything inside. The intestines he pulls them out and toss them is the dust-bin because we Humans don't eat them. They are dirty. (Sikhism lays reat emphasis on clealiness) The Baba Nanak looks for that stomach bag. Pull it out, slit it open and turn it inside out. Wash it to get rid of semi digested food from it. At times he can also see that her heart is still beating. Anyway, Baba-ji cops her body in to pieces the size depending on how he would cook it. Thanks.
