Mysteries behind the 3rd Chamber of Padmanabhaswamy Temple
There are 6 chambers in the temple (A,B,C,D,E,&F), out of these, chamber B is very closely associated with Sri Padmanabhaswamy. It is not the part of temple visit as this chamber houses many valuable items. The chamber B is considered as a highly mysterious, sacred, risky and dangerous chamber by the Trust members and other learned astrologers of India.
The door of this chamber is considered fixed with the naga badhnam/ paasam mantras by saddhus who lived during the reign of king marthandavarma in the 16th century. It is said that this door can only be opened by chanting "Garuda mantra" by powerful "saddhu/mantrikas or yogis" and no human effort is needed to open it. In fact, if any attempts are made with man made technology other than by chanting mantras, adverse effects are likely to occur in and around the temple premises. Also, it is said that the door will open only then when the "mantra" is chanted properly by some Sadhu otherwise the door will wreak havoc on those who try to open the door.
