Hello, Sai
please accept my condolences and extend them to the rest of your family. I am glad that you were able to perform the rituals for your dear grandfather both for his sake and for yours. I know that it was a hard task for your mother and her sisters to care for him during his final illness, but it was a blessing to them to be able to do so.
I hope that you will find peace in the coming days, and remember the many wonderful times that you had together.
Maria
