The mind can be used as a tool to clarify the mind. By identifying and overcoming its own illusions it can perceive and participate in reality. Aside from the mind and its contents, is there anything else that truly exists? If all that we have ever experienced is the contents of the mind, interpreted as personality, body and world, then a mind-shift can totally and radically change everything.

"The light of any lamp dispels in a moment the darkness of long kalpas [aeons]; the strong light of the Mind in but a flash will burn the veil of ignorance... Although the mind is void in essence, all things it embraces and contains." (Tilopa's Song of Mahamudra)

"To bring Peace to All, one must first discipline and control one's own mind" (Buddha)

"Normal consciousness is a state of stupor, in which the sensibility to the wholly real and responsiveness to the stimuli of the spirit are reduced. The mystics... endeavour to awake from the drowsiness and apathy and to regain the state of wakefulness for their enchanted souls." (Abraham Heschel)

"And we, with our unveiled faces reflecting like mirrors the glory of the Lord, all grow brighter and brighter as we are turned into the image that we reflect." (Bible, 2 Corinthians, 3:18)

"I salute the light within your eyes where the whole universe dwells; for when you are at that center within you, and I am at that place within me, we shall be One" (Crazy Horse, Native American Lakota Tribe) 

In regards to the issue of dialogue to clarify and liberate consciousness, which is an exchange of words, the I Ching speaks of the metaphor of "eating ancient virtue" (note: in the context of the I Ching 'virtue' means "inner brightness and connection to reality"). To just intellectualise things is like chewing food then spitting it out. We need to chew, swallow, digest and assimilate wisdom so that it nourishes and pervades the whole mind and cultivates an inner brightness that is illuminated by the Light of Reality.

Then "the strong light of the Mind in but a flash will burn the veil of ignorance". To achieve this "one must first discipline and control one's own mind". Then "the sensibility to the wholly real and responsiveness to the stimuli of the spirit" will re-emerge and "with our unveiled faces reflecting" reality rather than illusion we "all grow brighter and brighter as we" come to realise and actualise the Truth that we are. When each mind-stream experiences itself, the world and each other from this perspective we will all "salute the light within... where the whole universe dwells". When we are each "at that center within" ourselves "we shall be One".
