Where I am not a customer, where I am not a buyer. I will not sell even a single item, wandering around, holding the shadow of words.

Kabir suggests that his existence transcends any transaction of buying and selling. Since he is neither the customer nor the commodity, he will not sell even a single thing while merely wandering with the shadow of words. This profound message teaches us that the value of knowledge and the self does not depend on external trade or desires. It guides the mind toward freedom from material attachments.
