A starting point is to give everything a thorough clean and to clear clutter. Throw anything out that you don’t need any more and don’t have anything around that just gathers dust.
Your house should be an extension of your personality so have things around that reflect that. The possessions that you love are the ones you most need to keep. Keep it minimal.
The positive vibes that you give out will create positive energies. I like to burn aromatherapy oils and scented candles, some people use incense. I also like to play music that has a feel good element to it.
Laughter will raise the vibrations of your living space as will love.
Sage, as I understand it, is a cleanser which may remove negative energies. There are a wide range of incenses so it’s personal preference which ones you use depending on what kind of ambience you want to create. It’s the same with crystals – whatever you are drawn to is the one for you. Rose quartz is popular as it resonates with the heart and is associated with love. Amethyst is another popular stone. If you have access to a shop which sells crystals, I suggest you look around and ask the assistants to tell you what benefits different crystals bring and find out which ones are in your price range as some of them can be quite expensive.
