। ॥ ४४३ ॥
In plain words
This one is the individual instance: the gross body of Viśva. And since it is nothing but food transformed, this sheath is called annamaya — the sheath made of food.
Close to the Sanskrit
This individuated one becomes the gross body of this Viśva; and because of its being a modification of food, this sheath is called 'annamaya', made of food.
