Relaxation practice needs to be undertaken for a period of time; it is not like surgery, where something is removed from your body once and for all.
You can contact Sarvatajnana to discuss the evidence-based research available regarding your particular issue and the relaxation methods we offer to help you decide which relaxation course to choose. Only your personal experience over time will reveal the benefits it has for you.
As a rule of thumb, two to three months of daily practice and learning can give you a good idea of possible benefits regarding your specific issue, as well as your overall wellbeing. And regular practice is usually necessary to keep these benefits alive.
