The name Srivaishnavism (IAST: Śrīvaiṣṇavism) is derived from two words, Sri and Vaishnavism.The word Sri (Tiru in Tamil) refers to goddess Lakshmi as well as a prefix that means "sacred, revered", and god Vishnu who are together revered in this tradition.
The first is Sanskrit traditions found in ancient texts such as the Vedas and the Agama (Pancaratra), and the second is the Tamil traditions found in early medieval texts (Tamil Prabandham) The Sanskrit traditions likely represent the ideas shared in ancient times, from Ganges river plains of the northern Indian subcontinent, while the Tamil traditions likely have roots in the Kaveri river plains of southern India, particularly what in modern times are the coastal Andhra Pradesh, Karnataka and Tamil Nadu region.
The tradition was founded by Nathamuni (10th century), who combined the two traditions, by drawing on Sanskrit philosophical tradition and combining it with the aesthetic and emotional appeal of the Bhakti movement pioneers called the Alvars.
The debate then was on the nature of salvation and the role of grace.
The Vaishnava Aja Ekadashi is a holy fasting day that is observed on the ‘ekadashi’ (11th day) during the Krishna Paksha (the waning phase of moon) in the ‘Bhadrapada’ month of the Vaishnava calendar.
The ekadashi observance in the Vaishnava calendar may differ from that of the Vedic (lunar) calendar, however the rituals remain the same.
For those following the Gregorian calendar, this date falls somewhere between the months of August to September.
The Vaishnava calendar is mainly followed by Vaishnava Sampradaya and ISKCON temples all across the world.
On the auspicious day of Vaishnava Aja Ekadashi, Lord Vishnu and His consort, Goddess Lakshmi is worshipped with full devotion.
The day of Vaishnava Aja Ekadashi is very important for Vaishnava followers in India as well as abroad.
The greatness of this day is explicitly explained in many Hindu religious books and scriptures.
It is believed that by fasting on Vaishnava Ekadashi day, devotees are freed from all their sins and ultimately gain freedom from the cycle of birth and death.
