During a Distance Energy Work Session, you are free to carry on with your day, if you like. The energy will flow to you just the same.
I do suggest, however, that you consider which states of being may be more welcoming and allowing for receiving the energy from whichever distance session you signed up for.
There is benefit to pausing and being still during your session. You can quiet your mind or you can focus on the intent you had for the session. Either way, taking some time to focus inward and remove your attention from stressful thoughts and todo lists, even for a few moments, will always serve you.
And being in this state, I think, is beneficial for receiving Universal Energy.
So, if you do go on with other activities during your session, that’s fine. I would suggest you refrain from doing anything that is likely to lead to you being irritated, annoyed, sad, etc.
Maybe put that phone call to your challenging colleague/family member off until later. 🙂
