She reveals that she is planning to share her moments of struggle through an autobiography.
"Doing my best and leaving rest to bhagwan (god). I noticed, surrendering gives peace. Learning a lot through this process... actually most of my spiritual learnings are no more a concept, but now all are being experienced... actualised," Manisha posted on her Facebook page.
"Is it a curse or a by default a wish come true? Would be writing my thoughts on this process of discovery in my autobiography. I think I am ready now for it. There is lot to achieve," she added.
The 42-year-old, who hails from an influential family in Nepal, established space for herself with films like "Saudagar", "Bombay" and "Lajja".
She underwent her first session of chemotherapy earlier this month.
