We have often heard the term ‘Rakhi sister’ a lot. If you are also wondering who is a rakhi sister, then we have an answer for you. A Rakhi sister is not related to her ‘Rakhi brother’ by blood but by emotions and will. As the thread of Rakhi is not just limited to the ties of blood but the feelings shared by people, you can get a Rakhi tied on your wrist by your ‘muh-boli’ sister and enjoy the bond of siblings. The religious ceremonies of Raksha Bandhan with a Rakhi sister are the same as is performed with a real or cousin sister.
