## The Samvayanga Sutra
**Chapter 81**
**Commentary:** This image of a monk requires 81 days to complete. The first nine days, one offering is received each day. The next nine days, two offerings are received each day. This continues, increasing the number of offerings by one each day, until the ninth set of nine days, where nine offerings are received each day. The total number of offerings is 405 (9+18+27+36+45+54+63+72+81 = 405). Except for the time of the Gocharikal, the remaining time is spent in silent self-cultivation according to the teachings of the Agamas.
**[138]**
**380:** There were 8100 (Ekkasi-ti Man-pajjavana-nisaya) mind-knowers in the assembly of the Arhat. The Vyākhyāprajñapti states that there were 81 Maha-yugma-shat.
**Commentary:** The word "shat" here should be understood as referring to study. One should know from the Agamas, through the study of the various quantities of the Krit-yugma, Dvapara-yugma, etc., the form of the thought and the form of the internal study.

**Chapter 82**
**381:** In this Jambudvipa, or in any island, the sun traverses one hundred circles (mandala-sayam) twice. For example, once when it is leaving and once when it is entering.
**Commentary:** There are 184 circles (mandala) through which the sun travels. Of these, it travels only once through the innermost circle of Jambudvipa and the outermost circle of the Lavana-samudra. It travels through all the other circles twice - once when entering during the Uttarayana and once when exiting during the Dakshinayana. This sutra describes this in relation to the 81st sthānak. It should also be known that although there are only 65 circles above Jambudvipa, they are all referred to as "Jambudvipa" in this sutra, in order to explain the Dhātaki-khaṇḍa, etc., and to describe the area of the sun's travel in relation to this island.
**382:** The Shraman Bhagavan Mahavira was conceived in the womb of Devānanda Brahmani and then transferred to the womb of Shīla Kshatriyani after 81 nights and days.
**383:** The distance between the top of the Mahahimalaya mountain and the bottom of the fragrant mountain (Sogandhiya-kanda) is 100 yojanas. The same applies to the Ruppi mountain.
