Archeologists have found evidence of wine being purposely made as far back as 12,000 years ago. To say this wine was made successfully is not completely true. People did not understand the fermentation process until the invention of the microscope followed by the pioneering scientific work of Louis Pasteur in the late 1860’s when yeast was identified as the living organism and agent responsible for alcoholic fermentation. Today, winemakers kill off any yeast in the juice and use isolated yeast strains in pure culture form to make consistent palatable wines. Also, a baker’s yeast has been identified to be utilized for good bread making.
Yeast is naturally everywhere. We can’t see it, but it’s in our homes, on the trees and plants, it floats in the air and we breathe it every day. Although ancient wine and bread makers didn’t know exactly why, they learned to keep a bit of good wine or a portion of good dough around to be used as starters for new batches.
Yeast is a type of leaven. Nelson’s Bible Dictionary states, “Leaven was a common Jewish metaphor for an invisible, pervasive influence.” Christ Jesus warned his disciples, “Take heed and beware of the leaven of the Pharisees and of the Sadducees.” (Matt. 16:6, KJV) More modern Bibles have incorporated the discovery of yeast into their translations, for example “Be on your guard against the yeast of the Pharisees and Sadducees.” (NIV) The use of the word leaven signified that which could be seen, leftover wine or a piece of bread dough, however the word yeast signifies the need to beware of thoughts unseen.
We can see thoughts. We see thoughts of anger and happiness and as we fine-tune our ability to perceive thoughts, we allow our self to be influenced only by that which is conducive to our spiritual growth and understanding.
From 21st Century Science and Health, “Mortals evolve images of thought. They may appear to the learner to be apparitions, but they are mysterious only because it is unusual to see thoughts, although we can feel their influence. Ghosts and strange noises brought out in a dark séance either involve pranks or they are images and sounds evolved involuntarily by human mind. Seeing is no less a quality of physical sense than is feeling. Here it can be asked, why is it more difficult to see a thought than to feel one? Education alone determines the difference. In reality there is no difference between seeing and feeling a thought.
“The term ‘sixth sense’ has been used to describe intuitive vision, or knowingness, when really it is first sense. Our intuitive perception discerns essential facts. Science enables a person to read the human mind, but not as a clairvoyant. Science enables one to heal through Mind, but not as a hypnotist.
“How do we distinguish real thoughts from illusive thoughts? By learning what is the starting point of the thought. Real ideas flow from the divine Mind. Unreal thoughts, coming from the brain or from auras, are extensions of the human mind; they are an accumulation of imprinted mortal beliefs and experiences. Ideas are spiritual, harmonious, and eternal.”
