[Ndptbudd]

Any feedback or thoughts in regards to the 'energy'/'aura' I felt between my thumbs? Real, or just tricks of my mind/physically relaxed body?

Depends on the position of your hands I guess. I meditate with palms upwards and gently relaxed in my lap and one hand on top of the other.

I wouldn't pay too much attention to body sensations or experiences when meditating. They come and go, just keep your attention with the breath.

In general, its a good idea to seek instruction and feedback from an offline Buddhist meditation teacher.
