I’m fascinated by the positive changes in energy around my home when I’ve been decluttering – amazing. Please see here a bagua map describing the different ‘zones’ around a home alongside crystals that can be used to promote a more positive environment in each area – truly fascinating – and it works for me.
Please bear in mind that apart from using crystals to promote positive feng shui, increasing the amount of colour linked to an area has a similar impact e.g. a picture containing a lot of blue could be placed in the bottom left corner of a space (8) to bring more knowledge, wisdom and harmony.
