To interpret symbols and occult traditions generally a poetic mind is required since symbology means the bringing together of data through things standing for other things (from συμβάλλω, to throw together).
Poetry comes from the Greek verb ποιέω, to make, to create, to bring forth. In other words it requires a creative mind to be moved by the rich tapestry of ancient symbolism and nature's hidden (occult) secrets.
The prosaic mind by contrast will immediately and unthinkingly take issue with the free and open-ended deciphering of symbols, including the signs that words constitute, e.g. in green language, invariably preferring scientifically valid explanations that have been established through conventional (from cum together and venire to come: the coming together of men) means of acquiring knowledge such as that gained through the peer-reviewed university system.
Prosaic comes from prose, typically contrasted in modern academic discourse with verse (poetry), and the word prose is from the Latin prosa meaning 'straightfoward', 'direct'. The prosaic mind will thus scoff at and be generally offended by alternative explanations behind mainstream reality, politics, history, religion, science, instinctively preferring perceived straightforward explanations, e.g. those offered by the corporate media and established institutions.
Perhaps the battle for knowledge of the ages has largely been one fought between prosaic and poetic minds, the former being content only with five-sense reality and intellectualist logic, the latter tapping into their in-tuitive imagination to decipher life's mysteries and esoteric lessons.
