LSIT is based on the scientific foundation of quantum physics. This deals with holistic structures and their interactions. The high dynamics of life is achieved by constantly changing relationships and opportunities, combined with a high gain of experience. This improves the adaptability and the chances of survival. Everything is subject to a higher meaning communicated to us about spiritual needs. We are spirit-driven beings who inhabit a body subject to electrodynamic laws. Each action requires information and energy, which we call up about our intentions. Diseases can be treated with medication. These transmit certain healing information. The LSIT uses this information directly, without need of pills. That's what makes them so efficient. It is capable of initiating healing processes even in advanced diseases.
