Raksha Bandhan is a festival to celebrate one of the purest relationships in life. Irrespective of whether your sibling is a sister or a brother, the significance of your promise remains. It is a pledge to safeguard and always look out for your sibling, a promise as strong, as resilient and as precious as a natural diamond. He/she may annoy you the most, but is also the person who understands you and the one you share your deepest secrets with. Just like natural diamonds, the relationship between you and your sibling is timeless and only becomes stronger with the passage of time.
