Depending on the environmental conditions, the observer influences the water through his thoughts, whether it is consciously or unconsciously.
Intentions associated to words, to pictures, to music … are amplified.
A word or an image has an influence only because it is associated with a type of thought that is an intention itself.
It is this type of thought, when attached to an image or a word that influences the water.
For example, the use of a heart which is the symbol of love should positively influence the water, so we could expect to obtain beautiful crystals.
If we do the same experience with positive thoughts (intentions), then we should get even more harmonious crystals.
But if sending negative thoughts (intentions), would the crystals remain the same?
Sometimes, the observations are reproducible: the two photos of the green heart (without color filter): same water, two different blades, two minutes intervals.
