grounding and centering before reading


As to my understanding, doing meditation is one of the ways to clear your -ve energy, and leaves you brighter and "cleaner" (look into mirror and you can see). However, where does the -ve energy go? -- may be around your house, if they are not cleared completely.
How about using some sea salt near you while you meditate, burn some incense, aroma oil, candles...., or smudge your house afterwards with some sage. Hope these will help to prevent demages.


Have you tried meditating outside the house sitting on the earth under a tree? Maybe if you are grounded to the earth before you start, it might change things?
