In the movies thread I mentioned one called Water. It is an Indian made movie about a young girl that is married at 8 years old, whose husband dies and then she is widowed. She is sent to another "holy ashram" to live for the rest of her life.
I do not think that there is anything in it that would offend your mom. Indian made by a woman director, it avoids all the usual Hollywood excesses whilst handling the very serious issue you raise in a sensitive manner. May be check it out with her first but I am sure you are capable of watching serious movies. It is also very beautiful made and has some very touching moments. I have not watch your clip but these "widows" did until recently include child widows, thrown out by their families.
I agree with your wholeheartedly. If the BKs want their 900,000 to go to heaven, why do not they target, and serve, the estimated 40 Million widows; and all the other women and girls forced to do terrible things to escape poverty. Why do the BKs give gold chains to VIPs and chase the Presidents and politicians?
Well, perhaps there is the reason. May be they do not just want 900,000 but 900,000 with a good source of power or income! That would be my interpretation ... we will have to ask them. It is amazing how "practical" these "spiritual" people are. They always told me that BKs "did not do social work and charity", they only promoted their god and practise as it was "the highest service to humanity" according to them. If someone was suffering, that was their bad luck (karma) for their bad actions in the past according to the BKs. Not every one agrees with that ...
The white issue, I do not know the whole story. In India, white is also the cheapest as it is undied and unwoven. It is for the poor and, as you say, widows etc. Practically, it is a very cheap way of making a unifying uniform. BKs are generally called the "Brides of God or Brahma" not widows. As far as I am aware, the only issue to do with death is that they have "died alive" from the real world.
