We are humans and can not change the cosmic effects through pariharas or yatras. Only solution is Pray to your GOD whom your family does prayers. The divine power helps you. Read “AADITYAHRUDAYAM” daily. As Sun is in the star of Jupiter in 7th lord of 6 & 10, and in the sub of Moon in 6. As Sun is Karaka for father and Moon is karaka for mother, daily touch their feet and offer them your sweet words. It will make them happy.
As you know “Matru Devo bhava, Pitru Devo bhava, Acharya Devo bhava”. Parents are given such importance. After them only GOD comes. You will enjoy good results.
