A person works, spends energy (physical or mental), producing any kind of concentrated energy in the form of material products or creative works.  Further, he receives money for his work (also a form of concentrated energy of the state's material wealth in the form of money). Then he buys food (also a kind of concentrated energy (for example, the sun, in the form of photosynthesis). Then he cooks food, for example, on a gas stove ( gas contains concentrated heat energy), then a person consumes meat (protein), for example, which also contains concentrated energy. A person, consuming food, takes this energy, transforming it into vital energy at the same time. Then this cycle is repeated again: Person-Work-Money-Food-Its preparation-Consumption-Restoration. Moreover, the scheme of energy circulation will always be the same: energy consumption, its transformation and recovery. At the same time, the energy itself does not go anywhere and does not disappear. Just like it doesn't come from anywhere. Turned on the light bulb – spent energy. You've earned money, paid for electricity, and you can continue to consume electricity.  At the same time, electricity itself also did not come from nowhere, but was created, for example, with the help of water energy at a hydroelectric power station.

And the most interesting thing is that the person himself is a kind of energy expressed in matter. Everything that surrounds him is also energy and its various modifications. Thus, a person's life is transformed into the expenditure of energy, its transformation and further its recovery. But then human life itself turns into some kind of nonsense, since animals also spend a huge amount of energy foraging for food, and then, having obtained it, restore the spent energy reserves. Moreover, in this case, it does not matter what role the animal plays – as a victim or predator. Both spend their energy foraging for food. Only ruminants, for example, spend much less energy than predators, but it also requires only grass to restore it, and not protein (pure energy) in the form of meat. By the way, the grass also spends its energy on growth and receives it again in its pure form from the sun, converting it into chemical energy using photosynthesis. That is, here we see the same process: energy consumption – its transformation and recovery.

But then a natural question arises: What, a person is like an animal and a plant, if the principles mentioned above are the same? The answer is Yes, if its existence is limited to just that.  But man is a very complex being. It is distinguished from the animal by its thinking ability and ability to plan its actions. But thought is also energy, only of a slightly different kind, more subtle, not material. Moreover, just as with the expenditure of physical energy, it is necessary to restore it. However, in this case, just eating meat or bread is not enough. You need to consume the same type of energy that was spent. How? There are different ways. Some people have enough to read a newspaper, others a book. But in both cases, a book and a newspaper are one and the same type of energy – mental energy, transformed by means of letters and symbols in a concentrated form – into a book or newspaper (it is interesting to note that letters and symbols act here as transmitters of this very mental energy, i.e. they themselves are a kind of energy source, keepers of energy!). But this is also not enough for others. You need, for example, to visit the theater, where the actors, spending their energy, present a play written by the author, who, in turn, spent the same energy to write the play. Others need to visit a museum or art exhibition, which also stores the types of energy embodied in any rarities.

But that's not all. There are a very small number of people who are not satisfied with just restoring their energy. They're looking for something else. They start asking themselves questions: Who I am, why I'm here, what my mission is. In short, about Man, God and the Universe (these are all names of the same Energy in different qualities).
