## [79 First Chapter: Description of Narakas]
The depth of the Narakas' descent into the Bhavadharani is an immeasurable fraction of an angul (finger width) at the time of birth. The highest depth is 500 dhanush (bows). This highest measurement is in relation to the seventh earth. Their depth of descent into the Uttarvaikriyika is an immeasurable fraction of an angul at the lowest and 1000 dhanush at the highest. This highest measurement is in relation to the seventh Naraka-bhoomi (hell). The highest depth of descent into the Bhavadharani and Uttarvaikriyika of different Narakas should be known from this table:
| Earth Name | Bhavadharani Depth | Uttarvaikriyika Depth |
|---|---|---|
| (1) Ratnapraba | 7 dhanush 6 angul 15 | 12 angul |
| (2) Sharkarapraba | 15 dhanush 12 angul | 31 dhanush |
| (3) Balukapraba | 31 dhanush 62 dhanush | 62 dhanush |
| (4) Pankapraba | 62 dhanush 125 dhanush | 125 dhanush |
| (5) Dhumapraba | 125 dhanush 250 dhanush | 250 dhanush |
| (6) Tamahpraba | 250 dhanush 500 dhanush | 500 dhanush |
| (7) Adhasaptamapৃথিবী | 500 dhanush | 1000 dhanush |
The bodies of Naraka beings are not made of any of the six types of sahnana (conglomeration). They do not have any veins (arteries) or nerves (small veins), nor do they have bones. The definition of sahnana is the accumulation of bones. Since Narakas do not have bones, the question of sahnana does not arise.
One might wonder that the Sewart sahnana was mentioned for the Ekendriya beings, but they also do not have bones. The solution is that Ekendriya beings have an Audarik (formal) body, and the Sewart sahnana is mentioned in relation to that body. In reality, only the Asthinichayatmak (bone-accumulating) is sahnana.
In Prajnapana and other texts, Devas (gods) are said to have Vana sahnana, but that is also said in a secondary sense and only as a formality. Devas have the power to uproot mountains, and they do not experience any physical exertion or fatigue in this task. Therefore, they are called Vajra sahnani (diamond-like). In reality, they are Asahnanani (without sahnana).
One might doubt that "special power is called sahnana." According to this definition, it might be possible to consider Devas as having sahnana in the main sense. This doubt is contradicted by the principle, because in the same sutra, the definition of sahnana is given as "Asthinichayatmak," and it is clearly stated that in the absence of bones, Narakas do not have any of the six sahnanas.
Again, one might doubt that if Narakas do not have sahnana, how does their body bind? The sutrakar (author of the sutra) answers this by saying that their body binds like the Pudgalaskandha (matter-aggregates). The Pudgal that is anist (unpleasant), akant (unfavorable), apriya (unpleasant), ashubh (inauspicious), amanojna (unattractive), and amanam (unworthy) becomes the form of their body.
