I think India has more festivals than days in the year. Yesterday was Independence Day but also Varalakshmi Puja dedicated to the Hindu goddess of wealth and prosperity. The festive spirit continues today with Raksha Bandhan. This festival celebrates the relationship between brothers and sisters.
Today sisters will be trying a thread or bracelet (a rakhi) on their brothers' right wrists to wish them good health. Brothers then take on the responsibility to protect their sisters and give them a small gift in return.
If a brother lives far away, no problem - his sister can easily send him his rakhi in a special tear-proof and water resistant Rakhi envelope available at the post office.
Happy Raksha Bandhan to brothers and sisters everywhere!
