Hello all. I'm new to the forum and I wanted to share an experience of mine and get some feedback if I may. Years ago while in college, My roommate and I were kicking back on one of those lazy Sundays when I felt a tingling sensation in my right hand like the feeling you get when one of your limbs "goes to sleep". When I raised my hand to look at it, I noticed a white outline around my entire hand. My roommate then grabbed my hand in jest but didn't say if he'd noticed the white outline. Afterwards I asked him if he felt anything when he grabbed my hand and he said that it felt like he'd stuck his hand in an electrical outlet. I couldn't explain it then, and another friend said that it was more than likely my aura. I welcome any thoughts anyone might have.
What you saw is your Etheric Body.
According to the "Western Wisdom Teachings", the Etheric Body is an exact counterpart or copy of the physical body. It extends beyond the physical body some few inches. It is electric-like, made of ether. It vibrates every single atom of the physical body and thus keeps it alive.
Without the etheric body, the physical body could not survive a single day on its own. That's why at death the physical body starts to decay very quickly, because of the retrieval of the etheric body. The etheric body is connected to the physical body by what the "Western Wisdom Teachings" called a "Silver Cord"
Besides the Physical body and the etheric body,
there is another body called the "Desire Body" the so called aura, the seat of our desires, emotions and passions. It has an oval shape, like the shape of an egg. It penetrates, envelopes, and surrounds the two other bodies. It has rich bright multi colors, depending on the disposition of the individual.
The Etheric and the Desire body only requires a slight extension of the physical eyes to see them.
