Question: From what spiritual community's practices did Oberto Airaudi adopt the name of Falco?     
Context: Between the 11th and 13th century, the foundations of an independent Serbian literature was formed.  In this period, the direction and character of literature was built with an elementary system of genres in its main guidelines, with a selected and modified literary language.  Only with the works of Saint Sava and the development of the autocephalous Serbian church did the Serbian literature receive its content that would make it an equal and active participant in the literary life of the Orthodox Slavic world.  Hence, the 13th century was not only the new, but main stage in the constitution of Serbian medieval literature.  This stage ended sometime prior to the end of the century, with the ultimate standardization of the Rascian orthography in literacy and completing the creation of the main genres of the period: the Hagiography ("žitije") and Divine Service ("služba").  The main literary centres of the early Nemanjić state were finally established by the end of the 13th century: Hilandar, Studenica, Žiča, Mileševa, Peć; in which the supply of Old Slavic general literature was filled with works of Serbian, domestic literary workshops.  In the course of this century Serbian literature sought to reach the height of Byzantine-Slavic literature, to join the community.  The motive of these activities, its main driver, is in the creation of Serbian Orthodox cults, cults of the holy dynasty (the Nemanjić) and the autocephalous church.  In order to enter the world of Byzantine and European civilization of the Middle Ages it was necessary for Serbia not only to have its independent state and independent Church, but also to have its role in the general Christian culture of that time, especially participation in holiness, in a higher spiritual community, where the Serbian people was represented through "their [own] people".  Its own literature was thus a necessary expression of social and national independence, but at the same time integration in the spiritual ecumene of the Christian civilization through which it showed maturity and justified the political existence of the state itself on the world scale.  On this basis, all of the specificalness of the old Serbian literature developed, as well as its universal, global identity: specificities are expressed in the creation of general genres, mostly in the hagiographical literature, i.e. the so-called "ruler historiography"; far less pronounced in hymnography, in poetry, where the canons of Byzantine poetics are quite obvious.  The role of founding father of the independent Serbian literature is held by Saint Sava, the youngest son of Grand Prince Stefan Nemanja, founder and first Archbishop of the independent Serbian Church. The Findhorn Foundation is a Scottish charitable trust registered in 1972, formed by the spiritual community at the Findhorn Ecovillage, one of the largest intentional communities in Britain.  It has been home to thousands of residents from more than 40 countries.  The Foundation runs various educational programmes for the Findhorn community; it also houses about 40 community businesses such as the Findhorn Press and an alternative medicine centre. The Federation of Damanhur, often called simply Damanhur, is a commune, ecovillage, and spiritual community situated in the Piedmont region of northern Italy about 30 miles (50 km) north of the city of Turin.  It is located in the foothills of the Alps in the Chiusella Valley, bordering on the Gran Paradiso National Park.  The community has its own constitution and currency, the "Credito". Freemasonry in Russia started in the 18th century and has continued to the present day.  Russian Freemasonry pursued humanistic and educational purposes, but more attention is given to ethical issues.  It was a spiritual community of people united in an effort to contribute to the prosperity of the Motherland and the enlightenment of the people living in it. Asceticism ( ; from the Greek: "áskesis", "exercise" or "training") is a lifestyle characterized by abstinence from sensual pleasures, often for the purpose of pursuing spiritual goals.  Ascetics may withdraw from the world for their practices or continue to be part of their society, but typically adopt a frugal lifestyle, characterised by the renunciation of material possessions and physical pleasures, and time spent fasting while concentrating on the practice of religion or reflection upon spiritual matters. Rogozhskoe cemetery (Russian: Рогожское кладбище ; ] ) in Moscow, Russia, is the spiritual and administrative center of the largest Old Believers denomination, called the Russian Orthodox Old-Rite Church.  Historically, the name "cemetery" was applied to the whole Old Believer community, with living quarters, cathedral, almshouses, libraries, archives and the Old-Rite Institute (established in 1907).  Actual 12 hectare cemetery is now a non-denominational municipal burial site; the Old Believers operate a closed spiritual community in the southern part of the historical Rogozhsky township, while Russian Orthodox church operates church of Saint Nicholas, located between the cemetery and Old Believer territory. Oberto Airaudi (29 May 1950 – 24 June 2013) was an Italian philosopher and artist, who founded the Federation of Damanhur.  Airaudi also went by the name of Falco (Hawk), based on the Damanhur practice of adopting animal names.  He was born in Balangero, near Turin, Italy.

The Sri Aurobindo Ashram is a spiritual community (ashram) located in Pondicherry, in the Indian territory of Puducherry.  The ashram grew out of a small community of disciples who had gathered around Sri Aurobindo after he retired from politics and settled in Pondicherry in 1910.  On 24 November 1926, after a major spiritual realization, Sri Aurobindo withdrew from public view in order to continue his spiritual work.  At this time he handed over the full responsibility for the inner and outer lives of the "sadhaks" (spiritual aspirants) and the ashram to his spiritual collaborator, "the Mother", earlier known as Mirra Alfassa.  This date is therefore generally known as the founding-day of the ashram, though, as Sri Aurobindo himself wrote, it had “less been created than grown around him as its centre.”
