He bakes it, with the text (Vâg. S. I, 22): 'Let the divine (or God) Savitri bake thee!' for it is not a man that bakes it, but a god it is: therefore it is the God Savitri that bakes it. He adds: 'In the highest heaven!' He means to say 'among the gods,' when he says 'in the highest heaven.' He touches it: 'I will ascertain whether it is done!' thus (he thinks, and) for that reason he touches it.
