I have recently published two non scientific books:

The Internet Contact is about online encounters and internet scams containing the memoir of me and my wife.

From a Distance is a book on Sufism inspired by the six sentences below which I wrote down in summer 2023.

What matters

1.          Learn to limit yourself

2.          Everything you do, do it out of love

3.          Make decisions. They determine your destiny

4.          Look for the music inside of you and learn to love yourself

5.          There is only one earth in the universe, and the laws of nature prevail

6.          Ask yourselves where the water on earth came from, and you (must) believe 

What I wrote to my friend Tobias Diener about the 6 sentences:

I think it is important that people never stop thinking about essential questions that affect their being and that they also live up to their responsibility for themselves and their fellow human beings. In the meantime, I have the feeling that we are doing this less and less. "I think, therefore I am" is an important sentence for me in my life. Unfortunately, it no longer has that meaning. The 6 sentences are intended to be an aid:

1. But do we want further progress until we abolish ourselves and destroy our livelihoods once and for all? We should control our actions. This is the central statement of the first sentence.

2. Love. Is a feeling that we can develop not only for a person, but also for our work, something we like to do, etc. By love I don't just mean the love we have developed for our partner. Being in love is a state, not what love means.

Passion would have been another possibility that would have covered a lot, but love is still the best way for me.

3. You know yourself; no decision is worse than a wrong one. We can learn from mistakes. We should make decisions carefully. Every decision determines our further path. And I am very sure that the path we take will decide whether we reach a goal in the end.

4. I think music plays a role for every person and often determines our mood and can trigger feelings. I think its discovery is the most important thing people have ever done. To feel your own music within yourself and to accept yourself as you are or became is rarely achieved for yourself, but you should always keep trying.

5. We only have one earth, and it is the basis of our life. We should deal with it better. Our future does not lie on another planet, and we will never be able to bridge the distance not even of a light year. The fact that we can recognize that there are laws of nature is a central ability of our mind. And we should recognize that they apply on earth.

6. This sentence was the most fun for me, because it also contains some humor.

I think there are things that we can only believe and we will never really know. In this sentence, everyone should find what they believe. But we should never stop asking ourselves the central questions of who we are and where we come from.
