Why do I feel tingling sensations during candle rituals for aura cleansing?

Name: Prateek Bansal.

DOB: 2 January 1997.

Place: Delhi, India.

When I light candles or diya, I always visualize that the light from it will purify me and make me feel energetic. Is it linked to aura cleansing with fire? Also, I feel my chest and my back feel weird.
