The idea is implicit in buddhism, hinduism and jainism. This means that in the three dimensional universe at any given place there are, or there can be, beings and their environments, that are not visible to the human eye and/or to the human consciousness. They are said to be existing "on an other level of the material universe", this other level
is thought to be a level on a fourth axis of our universe. This idea of a fourth dimension of different levels beings and their different worlds has often not been very clearly enunciated in buddhism. Thus what in buddhism are called "higher worlds" is usually understood to be higher in the three dimensions of our world.
Nowadays we all know that there is no Palace of Indra above the blue sky. But did they know it also in the time of Buddha? This means: did Buddha and Arhats and Bodhisattvas know it?
There are sutras where Buddha says that a meditator, like himself, can rise into the air, rise into the space, and he can touch the Sun and the Moon with his own hand. Other meditators like Maudgalyayana visited other worlds and other levels of existence.
In sutras there are also descriptions of how some Devas, and other beings, manifested themselves here on Earth, i.e. made themselves visible to the Buddha. Apparently they came from other levels of the universe, these levels are popularly called "higher", and they are popularly described as being in the "upward direction".
In the buddhist sutras there is no clear mathematical model of a multidimensional universe, it is there implicitly. Or this model is the Mount Meru universe.
The buddhist, jain and hindu model of a multilevel spiritual universe was made more clear and more explicit by Madam Blavatsky and her followers in 1800's.
