From Svarga Loka downward to the lower realms, beings exist in increasingly dense astral states. The only exception is Bhu Loka, where both astral and physically embodied beings are found. Because Bhu Loka is the only realm that supports physical embodiment, it contains seven Dwipas, or Earth-like landmasses, to sustain such forms. The beings physically manifested on these Dwipas appear as human or human-like.

Astral beings of Svarga Loka are refined and light, whereas astral beings of the lower Lokas have much denser vibrations. This density often leads them to misunderstand or misuse divine laws.

From Mahar Loka upward, ego-driven desire falls away. The astral body becomes extremely subtle, and existence shifts toward the causal plane. Joy becomes intrinsic rather than desire-driven. Causal karma is resolved across these higher Lokas.

Beings of Satya Loka can be considered to be at the final frontier of evolution. Once all causal karma is resolved, they attain full liberation. Ego consciousness dissolves, and they merge with the totality of the Brahmanda, becoming one with Brahma. When such beings choose to re-enter creation after liberation, they are known as Avatars.

Beings of the lower Lokas can also evolve, but to do so they must take birth in Bhu Loka on one of the seven Dwipas. Earth offers the greatest opportunity for self-improvement. These beings may also choose to remain in their own Lokas and perform tapas there, often to gain power for self-aggrandizement rather than liberation.

Many astral beings, from both higher and lower Lokas, are capable of traveling to Bhu Loka.

Besides humans and animals, Earth also hosts astral beings. These include nature spirits such as Yakshas and Khetrapalas, the guardians of land, along with many other forms. Some of these beings are helpful, though they usually expect something in return. Others can be harmful and may cause confusion, disease, or disturbances.

Lower astral beings are often associated with psychosis, physical ailments, and misfortune. They tend to look for openings in the human astral body that occur when there is a lowering of prana. Such a lowering of prana can arise from uncontrolled emotions, whether overly expressive or suppressed, as well as from intoxication.

Astral beings from higher Lokas may visit Earth to support human evolution by offering protection and guidance. However, they are not fully purified, and on rare occasions they can be misleading. For this reason, the most reliable guidance comes from a fully self-realized Guru, though such a connection becomes possible only when a seeker has reached a certain level of inner purification.

Within Bhu-loka itself are the seven Dwipas, each containing physically embodied beings. Earth is the central Dwipa and the one we inhabit. Beings on other Dwipas have physical forms built from very different vibrational building blocks. They exist within specific sub-bandwidths of Bhu-loka that match their planetary conditions. Outside those sub-bandwidths, their matter loses integrity.
