Living for 100 Years
The human body is capable of much more than 100 years, but unfortunately the majority of people do many things in order not to live even this relatively short 100 years.
One of the most important pieces of advice I can give you is to stay in touch with your own body, mind and spirit, and if you keep all three in balance, 100 years is a very easy goal to achieve.
When I say to be in touch with your physical body, the manifestation of this can be felt on several levels in your life. Of course, you realize that you have a certain genetic stock, but what is good is to keep in mind that this genetic stock is constantly changing. In the same way that external factors can destroy this genetic stock, you can improve it "on the fly", so to speak. And by the way, you fix it. One of your body's wonderful abilities is its self-healing ability, but unfortunately, many people assume that healing can only bring their body back to a level they are used to, rather than improving it.
Another factor related to your body is your environment. You have quite a big influence on your environment: you have influence on your diet and on various environmental factors as well. This means that, for example, you will obviously not take a liquid or food that is toxic to you, because you know that it is harmful to your body. With the same attitude, you can improve many parameters. If you consciously pay attention to what you drink, what you eat, what environment you keep your body in during the day or at night, you can help this continuous self-healing process much more, which will ensure that the body you use will remain in its easy-to-use, disease-free state.
Speaking of awareness, let's move on to your mind. The purity of your mind is clearly reflected in the condition of your body. Unfortunately, on earth, they try to influence your mind in many ways, with many different methods, because whoever has influence over your mind can have a very big impact on your everyday life. For example, those who feel powerless in their lives often try to convince themselves that they still have power by trying to oppress or influence others. Pay attention to this and make sure to remind yourself every moment of every day of the enormous power you have over your own life. Consciously try to exclude the factors that affect your mind that you know, and allow in those that you feel will help your development and rise.
Just as with your physical body, with your mind, you cannot perfectly control every single parameter, and that is not the goal. Total control is just an illusion anyway, on the other hand, using your free will is critical.
Your soul and the rest of your being exist in this world in the same way as your physical body or mind. You must understand this to mean that if you are mentally in a pleasant, positive, light state, your physical world has no choice but to reflect that state and mood. From this point of view, one of the most important keys to your long life is your mental health. Your emotional world is a barometer and one of the indicators of your mental health.
If you see yourself often in an emotional state that is not your preferred mood, then that is an excellent indication that you should change something. In the majority of cases, a conviction or limiting belief of yours reveals itself that you have to deal with. Then when you realize how false it is, letting it go will restore your emotional balance.
You can imagine this in the way that the source of your being is a source of unlimited love, a source of unlimited pleasure, unlimited joy and enthusiasm, and the only thing that makes you not in this state right now is that limiting beliefs color, distort, shade this kind of light in different ways. Revealing and dissolving beliefs is not an easy task, but with persistent work you can get much, much closer to your own source. Notice how enthusiastic you are and how quickly time passes.
There is one very important thing about the passage of time that I suggest you observe. If you are doing something that you really like, that completely engages you, that inspires you, that you find pleasure in, then time just flies. You feel as if, say, 4 hours have passed in 0.5 hours. You won't believe your eyes when you look at the clock. On the other hand, if you are doing, or have to do, or feel like you have to do an activity that you don't like, then that 4 hours of work will seem like at least 12 hours. The most important lesson from this phenomenon - in answer to your question - is that when you feel that 4 hours 0.5 hours have passed, you are actually only 0.5 hours old. Unfortunately, this is also true for the other case: when you can age for 12 hours in 4 hours.
If you think about it, it is in everyone's interest that everyone spends their years on Earth as happily and efficiently as possible. That's why you shouldn't and shouldn't take it as a selfish goal to look for those activities in your everyday life that make you feel as good as possible and with which you can spend your everyday life as quickly as possible.
Let this be today's lesson.
