How to protect oneself from negative energy?

Question : How to protect oneself from negative energy?

Naran Sir:

Some people can make you unhappy and some others can sap all your energy.

Take the Bach Flower Remedies CENTAURY and WALNUT as well the Gem Remedy RUBY.

Alternatively, chant for 101 times "CENTAURY, WALNUT, RUBY" over glass of water and drink it.
