Bollywood actor Abhishek Bachchan's elder sister Shweta Nanda is in New York to celebrate Raksha Bandhan, which falls this Saturday.

"Shweta, my daughter, has come to be with us and to see the show, but more importantly to be with her brother on Raksha Bandhan," their father, veteran actor Amitabh Bachchan, informed on his blog www.bigb.bigadda.com.

Rakhi celebrates the bonding between brothers and sisters. On this occasion, sisters tie a thread on the wrists of brothers, who in turn renew their vow to protect them for life.

"What an endearing tradition Rakhi is. This bond of togetherness between brother and sister... this pledge to protect her and the affection from the sister with her blessings to the brother," Amitabh added.

The actor also spoke about the emerging tradition of 'Rakhi sisters and brothers' through which a brother-sister bond is maintained without having any blood connection.

"How wonderful to be able to nurture such emotion and to relate to it for the rest of our lives. The emergence of 'Rakhi brothers and sisters' has been so unique in our society. And many a time it has worked stronger than the one that has been ordained by birth. Unfortunate, but true," he concluded.
