One session and our problems disappear?

I didn't invest myself in this path to lie to you.
Again, it depends on you and your work, conscious and unconscious. An energetic treatment is a communion between three realities: the donor, the receiver and the universe. If you receive a treatment, but your mind doubts the quality or good reception of the treatment, it will not be a complete success and the results may even be diminished (or even cancelled) by your energies of doubt or negativity.
On the other hand, if your whole being welcomes the energetic care in consciousness and without any doubt, it can turn into a session with incredible results. Trusting your therapist is important, so you must choose him with the impulse of your heart and not that of your mind.
How many sessions does it take to get better?
We can't know that in advance. Often, one or two sessions are enough, but it all depends on the age of the problems.
If I don't have any improvements, will you refund me?
No, because it is a job and I invest myself with you, always being transparent in my approaches and explanations. You don't get a refund for a baguette you don't find good, while others will find it delicious? The same is true for therapists and energy care.
On the other hand, if the problem you are consulting on requires several sessions and nothing happens after the second session, I will advise you to see another therapist who may be more suitable for you in terms of energy.
Important : Energy care is not intended to replace or provide medical treatment, it is a complementary therapy.
