What do you think happened with our Chacras?

I'm a massage therapist by trade. Where I work, there is a receptionist, who I have seen signs of definite chemistry with. Yesterday, she was my client. Despite our possibly mutual attraction, I stay professional during the massage. So that is not a concern.

One of the modalities I practice is a form of energy work similar to reiki. It involves the Chacras. So, their presence in our bodies is familiar turf.

So, here's what happened:

At one point in the massage, our foreheads were very close. I was kneeling at the head of the table, massaging her neck. She was face-up. I was concentrating on the muscles I was working, and started to feel a charge building in my third-eye chacra. After a solid minute of this, a jolt of energy jumped from her forehead to mine. It didn't hurt, but it was palpable. In fact, she opened her eyes with this look of surprise. I asked "Did you feel that too?" And she said she did.

What do you think happened there?
