Celestial beings are of four main types:
- Mansion dwelling celestial beings (Bhavanvasi deva)
- Wandering celestial beings (Vyantar deva)
- Stellar celestial beings (Jyotishka deva)
- Empyrean celestial beings (Vaimanic deva).
The part of loka above the base of mount Sumeru is called upper loka. Only empyrean celestial beings (Vaimanic deva) habitat the upper loka, the other three types of celestial beings lives in the middle loka. There are sixteen heavens (Digambara belief, 12 in Swetambara) in the 6 raju region of upper loka as shown in fig. 6.4. After these heavens, nine Graiveyaka, nine Anudisha and five Annuttar celestial lands are there in a region of one raju. The region between the last Annuttar land and the first outer layer (vata valaya) is called the Eighth Land (Ashtam Prithvi) having a height of 8 yojana. The Sidhha loka, abode of liberated souls, is situated in the middle of this Eighth Land.
There are 10, 8, 5 and 16 subtypes of the four main types of celestial beings respectively. The mansion dwelling and wandering celestial beings have two kings (Indras) in each subtype so that there are 20 and 16 kings for the two types of celestial beings.

The first four excellent empyrean celestial beings (Ahamindra) are liberated after two births as human beings as a rule. The last fully accomplished beings are emancipated in the next birth as human being. A soul has to have a human body for liberation; liberation is not possible from celestial body.
