The OTZMA Method

Natural Way for Personal Safety

Personal Security

Day after day we hear about violent or other harmful incidents.

What hits the press is the tip of the iceberg. Most cases are “minor” and do not make it to the news. Nevertheless they are very shocking and traumatic to the victims.

We are all at risk and we are all exposed one way or another to harmful events. Our sense of personal security is often questionable.

The main question is - what do we do about it?

Do we let fear and anxiety control and manage our lives?

Do we live in denial?

Are we more frustrated and angry and let our rage lead us?

All of that is perfectly understood, yet it impairs the quality of our lives, health and our joy of living. BUT there is a better option…


Despite the fact that we cannot control everything, nor be prepared for all harms at all times, we can easily obtain a great set of simple intuitive yet effective tools that in a very short time will provide us with the understanding and know-how to prevent or minimize the risk of violence/exposure to danger, the ability to protect ourselves should we need to and to improve the overall sense of security and well-being. 

What is personal security and what is the sense of personal Safety?

Personal security involves the protection of our lives, health and property from a variety of threats to which we are exposed on a daily basis, be it Crime, Terror, Nature Disasters, Accidents or any other crises.

Whilst the level of our personal security can be measured by objective criteria, our sense of personal security is a subjective feeling.

This “feeling” was found to affect the quality of our lives with direct relation to our health and happiness. As such, personal security and our sense of Safety are essential ingredients in our well-being and should be addressed as such.

What do we mean by "Natural Way"

Often what can tip the scale in a time of need is our awareness, conduct and our physical, mental and cognitive response.

Our body and mind contain natural preserve mechanisms which can do wonders if we only let them.

Given the right conditions and practice, we can awake and evoke these abilities to serve us in times of need as well to enhance our abilities in our daily routine.

The good news is that our learning and practice protocol is also natural, flowing, enjoyable and transformative.


Our Mission is to restore and enhance your level of personal security as well as your Sense of Personal Safety, based on true and valid information and practice that will establish in a very short time the understanding and skill level to function and cope in a variety of reality based scenarios.

We will provide you with the proper and most Natural and easy to learn tools to be aware of yourself and your surroundings, to manage your feelings and emotions, to move, respond and protect yourself and your loved ones.

Otzma System contains all elements

Personal Security and Self Protection do not start with knowing how to fight!

It begins with awareness which enables proper conduct, attention to the surroundings and alertness.

Otzma System is fun to learn

Animals and humans alike acquire their hunting/chasing and fighting skills by means of play and game.

This is so efficient! So we decided to go back to our playground to teach ourselves the most basic and raw survival skills. Then add the more combative nature and stress management elements. Our goal is to feel good and comfortable, to be able to defuse tension and fear rather than overcoming it…

Otzma System is reality based

Otzma System was formed and structured based on years of experience within the martial arts world, tactical and combat experience, teaching methodologies and analysis of harmful events and violent incidents which taught us plenty on aggressor and victim behavior.
