Greetings of the day From Siddhivinayak Solutionss!!
The Simple answer is Karma
Along with the karma you can do some remedies for a peaceful life
Like Watering Daily to Peepal Tree, Feeding Wheat Flour and Sugar bura to ants, Feeding Fish with rice balls, Feeding cow
This will clear all your sins of the past life and help you boost the current situation in life
