Everyone has a smaller or larger collection of sea shells brought from one of the vacations in the house. And while there are some beliefs that it is very wrong to keep these objects in the house, because they represent the dead remnants of marine life, and therefore they can not attract anything good - but only bad energy, according to feng shui they are very useful. Smooth shells represent the energy of comfort, family. Prickly - protective energy. And each species is a symbol of well-being and positivity.
