In plain words
What you call existent is no better than the nonexistent, the objection runs: it serves no purpose, just like a donkey's horn. But serving no purpose does not make a thing unreal, comes the reply; and serving a purpose does not make it real.
Close to the Sanskrit
An objection is raised: even what is called existent is equivalent to the nonexistent, because it serves no purpose, like a donkey's horn. The reply is: serving no purpose is no reason for non-existence; nor, in the reverse case, does serving a purpose establish existence.
