Do the wise people speak or stay silent? The talkative ones are those who prefer to copy and paste the shared knowledge or experiences that belong to the wise ones, who have reached that knowledge or experience through meditation and contemplation. The truly wise ones who have been through that meditation do not prefer to speak.
The bold mind, who has dared release the knowledge out of the mines and out of the depths of their inner selves, may have a thousand things to tell, but still prefer to keep silent. The “Truly Wise” does not burn with the desire of advertising how wise they are and how much they know.
The one who “Knows What is Taught”, simply speaks and speaks, in order to maintain the image of being the wise one. They say it is necessary to keep silent in order to listen. In fact, keeping silent is not necessary to listen, it is utterly necessary to be “Truly Wise”.
