It is necessary to have the agreement of the owner (or the tenant) to undertake the geobiological harmonization of a house but it is not essential that all the inhabitants "believe" in the existence of invisible energy phenomena for this work to be effective.
I always try to involve the people who live on site, because the better they understand the nature of the energetic phenomena they are confronted with on a daily basis, the more stable the balancing of the frequencies of the site will be (because these people are themselves part of the equation).
It is clear that homeowners who are at least a little sensitive to geobiological radiation will be more aware of the energetic adjustments made in their environment. Residents who are not sensitive to these phenomena will probably remain a little unsatisfied, but will nevertheless benefit from the improvements made.
