Twenty volunteers participated in a pilot study on the effect of coherence practice on the ordering of crystallization patterns in drops of dried saliva. The hypothesis tested in this study was that states of high heart coherence would result in increased order and complexity in crystallization patterns. The study found that coherence practice increased the ordering and complexity of crystal structure in 18 of 20 participants. Hence, we believe the use of saliva crystallization patterns is a viable method for showing the effect practicing coherence induced by positive emotions has on the information embedded in bodily fluids. This study also demonstrated how heartfelt feelings of appreciation and compassion and a coherent state could change the structural patterns in the participants’ saliva.
