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.
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.
In the world of Nirvana (in all the worlds of nirvana), the body and consciousness are one. The body-consciousness in the world of Nirvana is called the True Ego.
The causal body, coupled with the True Ego, is also called the spirit of a person. The astral body, coupled with the spirit, is also called the soul of a person. The essence of a person is his soul. The essence of the soul is its spirit. And the essence of the spirit is the True Ego.
The words spirit and soul are often used as synonyms. In addition, the word spirit is also often called the mystical ascending energy: kundalini, the holy spirit. Sometimes the word spirit refers to any vital, mental or mystical energy in general.
What is called matter in philosophy and the three gunas are essentially the same thing.
World of phenomena. What is meant by matter in science (physics) is the matter of the world of phenomena, guna rajas.
Astral world. Like the matter of the physical world, we can also talk about the matter of the astral world. Astral matter in Hinduism is sometimes called drachma, drachma vibrations, vibrations of drachma, guna tamas.
Causal world. Like the matter of the physical world, we can talk about the matter of the causal. Causal matter is mystical light, guna sattva. Causal stores information about everything. Information in the causal exists in the form of mystical light.
World of Nirvana. According to the concept, Nirvana is inseparable, therefore it is not accepted to single out any components of it. It is customary to study Nirvana from the point of view of unknowability, universality, indivisibility, constancy, eternity, absoluteness. In the world of Nirvana, they place Absolute. There is also a clarification that the Absolute and the world of Nirvana are identical.
According to the law of conservation of matter and energy, neither energy nor matter can flow from one dimension to another. Causal, astral and reality interact with each other by the mechanism of identification.
Parallel universes (double universes, parallel realities, double realities) do not exist. The past cannot be changed.
Typical division of the worlds
God – by this word we will call an intelligent being living in heaven. There are different levels of heaven. If you list the heavens in order from top to bottom, you get something like this.
⦿ Absolute. The original highest authority. Brahman, Adi-Buddha, Atman. The absolute is indifferent to samsara. The true Ego of man is originally a part of the Absolute.
⦿ Heaven of the upper causal world:
● gods who have transcended knowledge (fourth dhyana)
● gods who have transcended existence (third dhyana)
● gods who have transcended space (second dhyana)
● gods of boundless space (first dhyana)
