Tattvarthasutra
In the first category, the term Indra is used for both Bhavanapati and Vyantara, while the other categories indicate the absence of Indra. In the Jyatishka, only Chandra and Surya are considered Indra. Since there are countless Chandra and Surya, the number of Indras in the Jyatishk category is the same. In the Vaimanik category, there is one Indra for each Kalpa. In the Sahasra Kalpa, there is Indra named Shakra, in the Aishana Kalpa there is Indra named Ishana, and in the Satakumara Kalpa there is Indra named Sanatkumara. Thus, in the celestial realms mentioned above, each Indra corresponds to the name of that celestial realm. The only distinction is that Ananta and Pranata are both considered as one Indra, with the name Pranata. Aharan and Achyuta are considered one Indra in that Kalpa, and his name is Achyuta.
Now, the earlier category states:
First, the gods of that category are said to have a yellow-colored form.
Bhavanapati and Vyantara are said to have four physical forms among the substances of the Jati.
For example, Krishna, Neela, Kapata, and Pita-Tej.
Describing the desires of the gods:
There are two kinds of thoughts, one related to the body and the other related to touch, sound, and mind.
The thoughts related to the beyond are not categorized.
