Hi Andreya,
I started EFT in 2005 and TAT more recently but I tend to use them in conjuction with Qigong and Quantum Touch - healing modalities to help me to ensure that I have no blockages and that the energy runs easily.
Warm hands ! Oh yes - as a diabetic, when I first started Qigong I had both very cold hands and feet but all the energy work has ensured that I have warm hands and feet constantly.
With Qigong you direct the energy through your arms to your fingers and palms and use it to help others heal. Quantum Touch is somewhat similar, as with a combination of breathing and running the energy into your hands you can produce really strong energy and again help others to heal themselves.
With both modalities you use intention and attention like TAT & EFT. This way you use your excess energy whilst also replacing your energy from the Universe, so you generally don't tire, or have too much energy and you remain grounded.
If your hands already get warm you are halfway there - anyone can learn to
help others heal. With the additional techniques people you are working on can often feel very intense heat, tingling, their bodies jerk or they make involuntary movements when you direct the energy to them - Qigong, or as you actally touch them in Quantum Touch.
Most satisfying though, is to get the feedback when pain vanishes, or depression lifts and physical problems mend.
Love and light
