Sonia Gandhi, or at least her late husband's family, is from a different family than Mahatma Gandhi but, being rich, powerful and famous, she is a regular target of the Brahma Kumaris. See, here, as usual.
The Rakhi ceremony the Brahma Kumaris do has nothing to do with Hindu tradition. It is just a rip off, as usual. It is either just PR, or if you believe in the other theory, a kind of occult practise they do on people to get close to them and bind them to the spirit of the BKWSU.
For such a corrupt country, India's judiciary usually has a good reputation and it is also gratifying to see how secular and principled real India is. It is not all tied up with spooks, spirits, mythology and bogus religion. A lot of it is very modern and future thinking.
