To find my way about in a village, I ask a resident for guidance. Which of the following instruments of knowledge is used according to the classical Indian school of logic (Nyaya)?

Asking a resident for directions relies on verbal testimony, sabda.

Sabda is knowledge gained from the trustworthy words of a reliable authority.

Here the guidance comes through the informant's statements, not one's own senses.

It is neither direct perception nor inference nor comparison.

Accepting a competent person's word is exactly the pramana of sabda.
