Can I just see auras overnight?

Q: Does seeing auras just happen like that, one day you wake up and see auras?

Eva's Response: For some people, yes, it can happen overnight. But it's rare.

For others, it's a skill that can be learned through meditation and training. This is an exercise that beginners can do to start the process.

Personally, I started seeing auras fairly spontaneously, after a period of trauma and intense spiritual growth.
