What is meditation and is it useful to everyone?

Meditation turns learned information into experience. At the first level, its goal is to calm the mind and keep it in the same place. It creates a space between the perceiver and the perceived, allowing you to choose roles in the comedies of life and avoid its tragedies.
This defensive distance is most often achieved through awareness of one’s own breathing or concentration on the Buddha’s form — a meditation called “Shamatha” in Sanskrit and “Shine” in Tibetan. Those who manage to keep this state of mind in the laboratory of meditation will gradually achieve the same in everyday life. This is the first step in development and a necessary basis for penetrating vision and more complex practices.
The second level of meditation is called “Vipassana” in Sanskrit and “Lhaktong” in Tibetan.
Here meditation has no form and is aimed at the very nature of the mind. When we are aware without any object of awareness, insight and understanding spontaneously arise.
Thus, meditation is the concentration of the mind on something and the clarity that arises from it.
Is meditation useful to everyone?
Diamond Way Buddhism meditations are designed for those people whose goal is Enlightenment. If someone just needs to relax, then other means are better suited for this purpose.
In general, meditation is for people who have enough positive impressions in the repository of consciousness, enough insight and joy, to withstand an encounter with their own subconscious.
For psychotic people, it can be dangerous to meditate, as they have a tendency to perceive their feelings and inner states too real and may have many uncomfortable projections.
In this case, chanting mantras and trying to act in a positive way is better than starting too much concentrated meditation. Only when you feel good without pills and you can work, live on your own and maintain relationships, the time comes for practicing meditation.Then, there are meditations that should not be practiced without the so-called Buddhist Refuge. It gives protection and creates a connection with the Buddha’s own nature, a connection with the Teaching, with friends following the same path, and with Lama, which provides Refuge.
Moreover, meditation can bring positive results only to those people who have sufficient foundation for the meditation they practice.
If complex meditations are tried too early, and beyond the framework of a proven step system, this may lead to the so-called “white wall” state, when a person feels calm, but in fact, rather sleeps.
Such a state can reduce intelligence and energy.
What we are striving for is awareness that is sharp and clear like a diamond.
