The beggar is a metaphor, standing for the person who ignores 'unconditioned' non-dual happiness, which is available at all times but is ignored. Distorted non-dual happiness is what we call suffering. They are two sides of the same coin, so to speak. Thus the true nature of happiness is non-dual.
What does this have to do with whether a word or words have meaning? The belief that a word or words have 'ultimate' meaning (when they don't) is a trap that continually prevents us from experiencing happiness because we get caught up in a search for 'conditioned' happiness, which ultimately always fails to deliver lasting happiness because it ignores the way reality is, non-dual and unconditioned.
Words are useful conventional tools but they and the actions of body speech and mind that they drive, in the form of the internal dialogue's quest for conditioned happiness, seem to create some temporary happiness sometimes, followed by the inevitable suffering which must follow, since all the temporary causes and conditions that needed to be assembled, are just that, temporary, and when reality no longer resembles the reality identified as a happy set of circumstances, happiness vanishes, only to be replaced by more flawed thoughts, words and deeds.
Much better to understand the true nature and use conventional language to point like a finger of compassion at the true, non-dual, ineffable nature, beyond words.
