Kabir ke dohe, 1, Preaching without experience

करनी बिन कथनी कथै, अज्ञानी दिन रात।

कूकर सम भूकत फिरै, सुनी सुनाई बात॥

Kabir Das says in this saakhi verse that a person who has heard wise sayings might be repeating them to others without really practicing the same, quite like a dog that barks without making itself understood.

A sadhak, a seeker, should be mindful to practice and should not preach without personal experience through practice. It is a waste.
