A human word and Water Crystals
People say that a human word carries a strong power. It is possible to stimulate man with a word, hurt him, stroke him, or harm him or her. On the other hand, people are tended to attach not so big importance to it, because it is, after all, "just a word", and it has no visible influence (at least, they think so...) except for a mood change of somebody we are just talking to. The human tendency to embrace materialism - when even people who aspire to achieve spiritual expansion, search more or less subconsciously for some immediate tangible effect (to catch it, see it, hear it, etc.) - contributes to the fact that people use words and thoughts rather carelessly. So people happily natter, curse, are empty talking besides their thinking which is even disproportionately worse...
