The beautiful Aishwarya Rai has a dosham in her horoscope and she is doing many things as penance. One such is tying a mangalsutra around a plantain tree!
Aishwarya already did a special pooja for sevvai dosham at a temple in Varanasi. This was arranged by Amitabh Bachchan and his family.
It seems Aish also has a mangalya dosham. In Hindu tradition, the 'kumba vivaham' penance for it is to tie a mangalsutra for a plantain tree or banyan tree.
This is done to strengthen one's marital bond and only after that is done, the lady can formally wed the man of her choice.
On the advice of the priest at Varanasi, Aish and her family have decided to do this kumba vivaham. There are so many handsome men standing in line, but Aish is to tie the knot for a plantain tree. The country needs a Periyar or two!
