How can I cleanse my aura and protect myself from negativity without blocking out positive energy?

Name: Karan. DOB: 2 September 1994. POB: Lucknow, India. TOB: 6:30 AM.

I’ve been wondering, how do I protect myself from negative vibes while still staying open to the good stuff? Sometimes I worry that if I shield myself too much, I’ll end up closing off positive energy too. How do I find that balance?
