Medieval Serbian literature: 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.

Sri Aurobindo Ashram: 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.”
