World of mahanirvana. When a bodhisattva gains the experience of liberation in general from all delusions, which can be in the world of phenomena, and in the astral, and in the causal, he finds himself in a state that he has nothing more to achieve, he has overcome all the experience that is possible. This state is called «buddha» and this state corresponds to mahanirvana. «Maha» is translated as «great». Since mahanirvana corresponds to liberation from all worlds in general, it is divided into only two levels: mahanirvana and mahaparinirvana. Mahaparinirvana stands for the great final destruction of worldly desires. Buddha Shakyamuni left for mahaparinirvana after his death. There is often a discussion in the sources on the question: "can a Buddha-personality return from mahaparinirvana as the same person?" – Yes. Because the buddha personality is free, it is free to choose whether to return from mahaparinirvana or never to return.

Levels of consciousness

Levels of consciousness

A person consists of several bodies. Physical body, Astral body, Causal body and True Ego (True Self).

Physical body is an ordinary human body. The physical body has a consciousness.

Astral body can be described as something similar to the reflection of the body in a mirror. That is, it is not a body, but just a reflection. That is, it is, and at the same time it is not. To see the astral body, you need to have astral vision. The physical body is so arranged that when a person uses physical eyes, he himself, by virtue of a certain mechanism of communication between the astral body and the physical body, suppresses astral vision in himself. However, the ability to see with astral vision is not something unattainable. This ability develops in meditation. The astral body has its own consciousness. This consciousness of the astral body is correlated with what in science is called the subconscious (unconscious). The astral body, separated from the physical body, is also called the ghost body. There are beings who have only an astral body, but no physical body. Such creatures are simply called ghosts. When it is said about a person that a demon has moved into him, it means that a being of the lower astral (ghost), who does not have his own physical body, has superimposed on the astral body of a person or has taken (replaced) the place of his astral body.

Causal body may outwardly look like a ball consisting of plasma, similar to a ball lightning, or, to put it even more precisely: just a ball of light, just light as a ball. The causal body also has its own consciousness. This causal consciousness is correlated with what in science is called superconsciousness (deep unconscious, preconsciousness). You can see causal consciousness like this. If you recall a case when you forgot something so well, for example, the name of an old acquaintance, that there is absolutely nothing in your head. You're trying to remember. You make a mental effort. And suddenly a far, far spark flashes in my head. "I know!" You have not yet remembered what exactly, but you already know that it is in memory, and you know that this information will soon come from the depths of memory. So this spark is the causal consciousness. What is called in psychology the "collective unconscious" is the entire lower causal world as a whole.
