The harm of fear is that we fear in advance for a very long time. Fear has not yet come, and we have already spent all the energy and exhausted forces. With an effort of will and mind in advance to hope for a positive outcome. If the outcome is negative, the torment will be five minutes. If you suffer in advance, stress can last for days and weeks.
Slowing down, time turns into light, then into matter. The growth of the mother's mass under the influence of gravity causes a thermonuclear reaction, again dispersing energy and turning it into time and light.
There is a nuclear reactor inside a person, when this reactor overheats, fear will turn on. To the reactor does not overheat, you need to rise and act, then the fear will disappear and the soul will be very happy. Fear drains excess energy when a person has no goals worthy of love.
Inside man is illuminated by the sun. If this energy is not used for growth and movement, there is negativity and fear. Fear is like a radiator, something that drains excess energy. If fear is turned off but growth is not turned on, the system will burn.
If you are tired when you run, it means that you are running incorrectly. Real running is something like an electric generator and an inductor, it charges energy, not drains it. So in life, if you get tired of what you're doing, it means you're doing something wrong.
Love is an ecological niche. A person falls in love and this becomes his source of energy. The loss of love creates depression, a person metaphorically dies, but then finds a new ecological niche, and resurrects body and soul.
