Answer 1

to maintain the good relationship between brothers and sisters

Answer 2

there are two reasons
1. it's from mahabharat , jb krishna ji ko ek bar chot lg gyi thi to dropadi ji ne unhe apni sarii m se ek chota sa kapda phadkr unke hat pr bandh diya tha .. phir jb dropadi ji ka korwo ne apman kiya tha tb krishan ji ne unki rakhsha ki thi
2. bhut phle ki bat h jb rani karnavati ke upr hmla hone ja rha tha tb unhone bina dhrm aur jati ko dekhkr samrat humayu ko rakhi bheji thi
phir samrat ne unki rakhi swikar krke rani ki raksha ki thiii

tb se hi rakhi ka tyohar manate h
