In Hinduism, the universe is just one of an infinite number of universes, all of which are part of a single, infinite multiverse. The multiverse itself is infinite and eternal, and each universe within it is also infinite and eternal. There is no beginning or end to the multiverse and no beginning or end to any of the universes within it.
Each universe is filled with an infinite number of beings, including humans, gods, and demons. There are an infinite number of worlds within each universe, and each world is inhabited by an infinite number of beings.
The multiverse is divided into three main regions: the material world, the spiritual world, and the un-manifest world. The material world is the world we live in, which is made up of matter. The spiritual world is made up of energy and is the realm of the gods and other spiritual beings. The un-manifest world is the realm of the absolute, which is beyond all duality and is the source of all reality.
The material world is governed by the laws of physics, while the spiritual world is governed by the laws of karma. Karma is the law of cause and effect and governs all actions and their consequences. The un-manifest world is beyond karma and is the realm of pure consciousness.
Human beings are born into the material world and spend their lives in it. However, at the time of death, they leave their bodies behind and enter the spiritual world. In the spiritual world, they are subject to the laws of karma, and their actions determine their future lives.
After some time in the spiritual world, they are reborn into the material world in another body. This cycle of birth and death is known as samsara.
The goal of Hinduism is to escape from samsara and achieve liberation (moksha). Liberation is the state of complete freedom from the cycle of birth and death. It is achieved by realizing one’s true nature, which is pure consciousness.
There are many paths to liberation, but the most common is the path of yoga. Yoga is the practice of self-control and discipline, which leads to the development of concentration and meditation. Through concentration and meditation, one can develop a relationship with the absolute and eventually achieve liberation.
