Long since the Slavs, among whom the water-lily symbolized fidelity and separation, there was a belief that these unusually beautiful flowers conceal a great danger in themselves. People sincerely believed that a man who, without a charm, dared to approach the pond to tear off the egg-box, condemned himself to death, since mermaids would certainly drag him to the bottom. But even if he succeeds in taking possession of the flower, then from this moment the water spirits will begin to harm and spoil the life of this person. In addition, yellow cans were not bought from hand, because it was believed that with them a person gets the trouble and trouble of the one who sold him flowers.
