A single session is powerful and efficient in itself because the blocks will be cleared
permanently.
However, if you have been hanging out there with blocks in your energy for one, two, three decades...

*If you opt for a follow-up of several sessions, I recommend spacing out the sessions for a period of ten days to six weeks on average to soak up the new vibration.
