Logo design for a non-profit education organization, for hypnosis in medicine

Hello every freelancer! I am looking for some help creating a logo for a non-profit organization I am creating right now. The goal of the organization is to develop, promote, and support medical hypnosis in our medical studies! Hypnosis is a technique used in all medical specialties, but also by dentists, to relieve symptoms such as pain, anxiety, phobias, stress, addictions. It uses the power of the mind to heal the body, and the feeling when undergoing hypnosis = trance is a sense of deep relaxation and unicity with the person's environment. In this 21st century, a group of young medical students have altogether decided to develop this tool and fight the suffering of our patients. A problem that doesn't bother you so much anymore is not so much of a problem anymore! =) The first event is a FREE conference for students, residents, and doctors in July. We need some support for the design part, and it starts with a logo! Please help us make this world a better place! The name of the association is "Hypnocrate" in French, which means Hypnocrates in English, coming from the father of medicine Hippocrates. I have attached some ideas of drawings I have made myself! The freelancer with the best logo will be rewarded on our website once it is online of course! Thank you!
