In 'Geeta' you can find this slhoka
" Karmanevadhikaraste Mafaleshukadachan"

Karmanevadhikaraste: On karma certainly, you have right, Mafaleshukadachan: but not on fruits, anytime. What this verse is saying that we don’t have right on the fruits. this lady is good example of that and you capture the scenario perfectly. we have to do only our part best rest of all god is sufficient for us.

As she has planted, so does she harvest; such is the field of karma.
