The Noble Order (Sanskrit: 𑼅𑼂𑼫𑼱𑼪𑼴𑼙 or Āryasamāja) is the central regulatory and governing body of Buddhism in Siban. It also exercises a considerable amount of control over the customs, traditions, morals, and standards of Sibanic society. Because of this, it serves as a counterweight to the absolute authority of the Protectorate over the world. It is headquartered in the Dharmic City of Arjamargo, one of the autonomous, monastic-controlled settlements. 94% of Navodra practices Buddhism.
While all monastics have to be registered with it, not all monastics are part of the order. It is more of a regulatory body than an organization to be part of, though only monastics in good standing with the Order may become part of its ruling body. The governing body of the Order is known as the Dhārmikanikāya (𑼤𑼴𑼂𑼪𑼶𑼒𑼥𑼶𑼒𑼴𑼫 - Righteous Assembly) and consists of all the mahācāryas of Sibanic Buddhism. Each mahācārya (𑼪𑼲𑼴𑼗𑼴𑼂𑼫 - great preceptor) has his own saṃgha (𑼱𑼁𑼕) or monastics and lineage/s under his tutelage. A saṃgha cannot be formed without the approval of the Dhārmikanikāya, and all monastics are required to be part of a saṃgha. Each saṃgha has its own rules, regulations, structure, and practices.
A saṃgha as used by the state and the Order refers to a group or lineage under a mahācārya. It can be a sect, organization, institute, monastery, temple, or any other grouping.
The Order also has oversight over other religious traditions. No other form of Buddhism officially exists or is allowed in the planet except for what is sanctioned by the Order.
At the helm of the Dhārmikanikāya is the Mahavajrācārya (𑼪𑼲𑼮𑼙𑽂𑼬𑼴𑼗𑼴𑼂𑼫 - Great Vajra Preceptor), who represents all Buddhists in Navodra. He is almost always part of the retinue of the Protector, usually seated or positioned to the right. He leads all rituals performed on behalf of the state or the Protector, except for when the Protector is the one performing them. The Protector appoints the Mahavajrācārya with the consent of the Dhārmikanikāya.
Being the organizer of a state ritual or ceremony means choosing who will perform the rites, to whom offerings will go, in which temple or location it will be held, and what rites will be performed. For example, for the annual rite for the protection of the state, a deity has to be invoked and their protective rite has to be performed---being the organizer means your deity of choosing will be the one to whom all the attention will go to. It is a way of promoting one's rites and temples. The more patrons one have, especially from the elite, the more influential one's sect becomes. This also means stabler and significant revenue streams. Thus, the different sects, schools, and movements have always vied for the right to organize specific rituals annually, which is determined by a rigorious, tripartite selection process, wherein the Planetary Council, the Legislature (Council of Lots and Council of Banners, specifically), and the Dhārmikanikāya, usually in the form of smaller joint committees to expedite the process, have to create a shortlist of three potential organizers (either a specific person or an organization as a whole) from which the Protector will choose by sortition in a public ceremony.

In Sibanic Buddhism, only an ācārya (𑼅𑼗𑼴𑼂𑼫 - preceptor) is allowed to perform rituals on behalf of others or publicly. Being a monastic does not entail this right. An ācārya is one of the leaders of a saṃgha and has multiple monastics of lower rank under him. The ranks and titles of "esoteric right" take precedence and are above exoteric ones; one does not receive ranks and titles of esoteric right until one has accomplished the exoteric hierarchy. The rank of ācārya is a category, and there are several grades of ācārya in Sibanic Buddhism; ācāryas may be under other ācāryas in this system.
The primary job of an ācārya is to perform rituals for their respective dominions and the state at large. The ācārya of the main temple of the capital of a dominion, for example, serves as the chief officiant for all religious ceremonies of that dominion. The Order supervises the customs, traditions, morals, and standards through this system, and the main temple of each city serves as the power center of the Order in that area. It is not unusual for secular officials to consult their respective main temples before making important decisions, and new officials customarily visit their main temple upon their appointment. It is customary for new governors to visit the main temple of their dominion and spend a few days in seclusion with the religious hierarchs of their dominion.
Arrests, prosecutions, indictments, and judgements are usually brought before the temple who has jurisdiction over their area before they are executed, though not a legal requirement. This is because an ācārya may petition their Mahācārya to nullify such when they find it contrary to their local customs and traditions or some religious precept or standard. Mahācāryas have the legal privilege to nullify secular decisions, subject to appeal to the Dhārmikanikāya and, ultimately, the House of Settlements. It is customary for appeals to first go through a body superior to that of the nullifying official, which is the Dhārmikanikāya in the case of a Mahācārya.
