I've continued to use the same technique, but went to bed the other evening without thinking about it. Too lazy to get up again, I just visualized the pendulum hanging above me and waited.
Sure enough, in my vision it began to swing and I felt the tied up energy easing off.
Working with Quantum Touch®, their online community
has often discussed distance healing applications and how energy tends to do what we intend it to do, so I wasn't really shocked by my visualized pendulum doing its job as if I were holding the 'solid' version there.
So far so good on sleep and sciatica.
