Monk/Vaishnava monks

==Vaishnava monks==
Similar in appearance to Buddhist monks, monks from the International Society for Krishna Consciousness (ISKCON), or Hare Krishnas as they are popularly known, are the best known Vaishnava monks outside India. They are a common sight in many places around the world. Their appearance—simple saffron dhoti, shaved head with sikha, Tulasi neckbeads and tilaka markings—and social customs (sadhana) date back many thousands of years to the Vedic era with its varnasrama society. This social scheme includes both monastic and lay stages meant for various persons in various stages of life as per their characteristics (guna) and work (karma).
ISKCON started as a predominantly monastic group but nowadays the majority of members live as lay persons. Many of them, however, spent some time as monks. New persons joining ISKCON as full-time members (living in its centers) first undergo a three-month Bhakta training, which includes learning the basics of brahmacari (monastic) life. After that they can decide if they prefer to continue as monks or as married Grihasthas.
Brahmacari older than fifty years can become sannyasi. Sannyasa, a life of full dedication to spiritual pursuits, is the highest stage of life in the varnasrama society. It is permanent and one cannot give it up. A Sannyasi is given the title Swami. Older grihastha with grown-up children are traditionally expected to accept vanaprastha (celibate retired) life.
The role of monastic orders in Indian and now also Western society has to some extent been adapted over the years in accordance with ever-changing social structures.
Madhvaacharya (Madhvacharya), the Dwaita philosopher, established ashta matha (Eight Monasteries). He appointed a monk (called swamiji or swamigalu in local parlance) for each matha or monastery who has the right to worship Lord Krishna by rotation. Each matha's swamiji gets a chance to worship after fourteen years. This ritual is called Paryaya.
