Raksha Bandhan is a hindu festival which celebrates the love of brothers and sisters. It is celebrated in India, Mauritius and Nepal. It is also known as Rakhi Poornima or Rakhi. Here is a great collection of Raksha Bandhan images and pictures online.
Raksha Bandhan in Sanskrit means 'the knot of protection'. Hence, a Rakhi thread is tied by the sister to his brother and she prays for the well being of her brother.
