If the pressure in your head is getting worse with the Conduit of Light exercise (see Thriving As An Empath for those of you unfamiliar), please make sure that you are grounded first.
Its a step that I have added in as the first step recently. It is making a big difference for those people who were reporting issues with the exercise.
Imagine that you are growing roots from your legs, through the soles of your feet, deep deep down into the center of the Earth. Theyre flexible too, so that you can lift your feet and the roots will follow you. Try it at home first then youll be able to do it while you carry on a conversation too! It may feel a little weird at first to do this while you are in any form of moving vehicle but that will pass with practice! Its your imagination - make it work for you and keep practicing.
Let me know how you get on.
