Hi,
I don't know her but pray for her speedy recovery. I chanted this Death defying mantra once and wish that everyone does it once for her sake.
"Triyumbakum yajamahe sughandim pushti vardhanum
pooruva rukamiva bandhanat mrityorr mokshi mamrutat"
The Maha Mrityunjaya Mantra is very much a protector from accidents, mishaps and daily calamities in the modern busy life.According to Rishi Vashishtth, Mahamrityunjaya Mantra has 33 alphabets which represent the powers of the 33 deities. These 33 deities are - eight Vasus, eleven Rudras, twelve Aadityas, one Prajapati and one Vashatkaar.
These 33 deities are present in different parts of the body of a person. When this Mantra is chanted divine forces in the body are activated and they protect the person from diseases, weakness and death.
I think One mala Jap will be more then enough.But should be in proper devotion.
