Srimathe Ramanujaya Namaha,
With Acharya ThiruvAdi Bhalam and Velukkudi Sri Krishnan Swami’s Aasirvadham, Adiyen would like to share some details regarding the initial question “…………..Will there be any symptoms while atma is leaving through sushumna nadi, which can be noticed by the people present in that place.”
when the particular BhaddhAthma leaves the existing body, and if it exits through Sushumna Naadi (nerve) ONLY, at that time only three people know about it.
1) That particular BhaddAthma,
2) JagadAcharyAr Swami RamanujAr and
3) ThiruMoghur Perumal
will know that the particular Athma will Travel through Archaraadhi Maargam, and the Athma’s existing Sthoola Shareeram (body) will be shed down and BhagavAn gives a different Sookshma Shareeram for the travelling purpose through Archaraadhi Maargam. Then this Sookshma Shareeram is also shed down in VIRAJAI Nadhi (final Holy River) that separates Samsaram (leela Vibhoothi) and SriVaikuntam/Moksham (Nithya Vibhoothi), after that the MukAthma is given a different body called “Aprakrutha Shareeram” which is non-deteriorating body for Nithyakainkaryam to BhagavAn-Thayar-Acharya for Bhagavat Preethyartham.
As said by PoorvAcharyas In Swami RamanujAr Dhaati Panchakam Slokam as:
விஷ்ணு லோக மணிமண்டப மாரக தாயீ இராமனுஜோ விஜயதே யதிராஜா ராஜாஹ (Glories glories to Swami RamanujAr who is the guiding light through the Path that takes us to BhagavAn Sriman NarayanAn’s Mani Mandap (Paramapadham))
What a beautiful TOP CLASS SWAMI RAMANUJAR SAMPRADHAYAM and anyone while following in any other Sampradhayam says as “Srimathe Ramanujaya Namaha” one time with grattitude get the same benefit as the one in Ramanujayar Sampradhayam.
If any other Bhaddathma in Samsaram like parents friends family need to know if another BhaddhAthma travelled through Archaraadhi Maargam or not can be known by feeling only. Like if one touch with hand on the head Ucchi of the Pious Bhaddathma immediately on the Charama Shareeram (after dead), they can feel it as hot. That is the only symptom that any one of us feel. So it means that particular Athma went to Moksham (SriVaikuntam) through Archaraadhi Maargam. If other portions of body are hot like the ullangaal (bottom side of feet) or chest etc….then all these indicate that the Athma exited through different Naadi’s (nerve) other than the Sushmna Naadi and hence will not be able to go through Archaraadhi Maargam and went to some other lokas within this Samsaram, like us from past birth to this Birth.
