Is it safe to do aura cleansing with fire during emotional breakdowns?

Name: Simran Kaur.

Place: Amritsar, India.

Sometimes when I feel too emotionally heavy, I burn sage or just stare at the candles. It helps but the other day I came across aura cleansing techniques with fire. And I realized that that's the same I have been doing, is it true? How does it help?
