Earlier this year, Bollywood veteran, Sonali Bendre was diagnosed with metastatic cancer. Although an uphill battle ever since, Bendre has fought the good fight and triumphed over the deadly disease. And through her entire cancer crusade, her sister has been an ally and close comrade.

In a recent heartfelt Instagram post Sonali thanks her sister, Rupa Tai for her unwavering support and says,

“She has been my rock...my person... Rupa Tai was involved in my journey from when I was diagnosed to the time I was deciding the course of treatment to packing her bags and coming with me to New York. She was there from get-go.”

Sonali's thank you letter to Rupa Tai is truly a beautiful example of what a blessing it is to have a sister like her.

"An older sister is a friend and defender – a listener, conspirator, a counselor and a sharer of delights. And sorrows too. – Pam Brown" Rupa Tai has been all this and more. She dropped everything in a heartbeat to be with me on this journey. She has been my rock...my person... Rupa Tai was involved in my journey from when I was diagnosed to the time I was deciding the course of treatment to packing her bags and coming with me to New York. She was there from get-go. Her transition from one role to another was seamless. A dictator when I needed to eat right or take my meds or an empathetic counselor alternating between giving advice and offering silent support when all I needed was to be alone with my thoughts. She was around. She was with me and by me, at all times. Sisters share a special relationship. We are literally an extension of each other. For bad days, her presence did the trick and the good days...well, it just got better! We have now returned home - to our respective families and lives, but us together in New York for those 6 months...I am forever indebted... #SwitchOnTheSunshine #OneDayAtATime @ranadiverupa
