। ॥ ३०१ ॥
In plain words
When the silver vanishes, the shell does not: only the silver was ever cancelled. In just that way, the thing called avastu, the non-entity, is the cause of this world being superimposed.
Close to the Sanskrit
Just as there is indeed no cancellation of the shell, as there is of the silver, so that which is designated 'non-entity' — that is the cause of the superimposition of the world.
