..... What this strict vaishnava means?
Dear DD, I used the term "strict" a little carelessly. I should have said "Sri Vaishnavas who are not casual".
Like Upanayanam is an important samskaram for the body, the most important samskaram for the jeeva, according to Sri Vasihnavam, is Pancha Samskaram, aka Samasrayanam. This samskaram, in as much as it is for the jeeva, is for both genders. It is administered only by a traditional and qualified acharya and this person remains one's acharya for life. Samasrayanam also means approaching an Acharya. Even though Bhagavat Ramanuja had several acharyas, and even though the most important among them was Thirukkoshtiyur Nambi, it is Periya Nambi who is considered his acharya and is in the acharya lineage because it was Periya Nambi who performed Pancha Samskaram for him.
The five Samskaramas of Smasrayanam are:
- Tapa samskaram -- marking the shoulders with Shakhu and Chakram by the acharya,
- pundra samskaram -- marking thiruman & sri choornam in twelve places in the body with appropriate manthras, by the acharya, from this time onwards, the male Sri Vaishnavas are supposed to wear 12 thiruman Sri Choornams with proper manthras
- Nama Samskaram -- taking the dasya namam, from this time onwards, they should refer themselves as only Ramanuja Dasan
- manthra samskaram -- upadesham of three rahasya manthras, (i) Thiruvashtakshram, (ii) Dwayam, and (iii) BG Charama shlokam (for females the manthras are slightly changed as they are forbidden from hcanting pranavam
- Ijyai samskaram -- Initiation into performing Thiruvaradhanam for Sriman Narayana (only for men, women can only assist men in this task)
A detailed writeup on Pancha Samskaram can be found
here.
For Vadakalis there is one more step required, and that is Prapatti -- unconditional saranagathi.
Even though "anya-devatha" worship is not even supposed to enter the radar screen of Sri Vaishnavas, the observance of these rituals brings home the importance of the traditional practices. This is why you find a profound change in their behavior. Sri Vaishnavas who are lackadaisical about these matters suddenly become quite serious.
Partaking food is another serious matter. Food must be prepared by Sri Vaishnavas who have already undergone Samasrayanam. It must be offered first to Sriman Narayana through a proper Thiruvaradhanam performed in the prescribed manner. Very orthodox Sri Vaishnavas will not even eat in Matams as they consider the acharam/anushtanam of kainkaryaparas wanting. Some of them won't even accept theertham from even Sri Vaishnava temples unless it is right after the conclusion of "Satrumurai".
Cheers!
