Any astrological influence can be overcome by counteracting various influences. The Vedic King’s did regular sacrifices , for the sake of purification and avoidance of ill effects because of their involvement in some inauspicious activities of the citizens.
Similarly, our free will meanders through life with certain  somethings with the effects of inauspicious influences from.previously performed impious actions and the Vedas recommend sacrifice and pioneer actions to  countact the insuperable effects .

What to speak of devotional acts …which are trancendentally auspicious  and have the effects of eradicating all the effects of pious or inpious actions from many lives , and reawaken the original pure spiritual form of the living being , the effects of all.types of Karma are removed .
Thus, life is never predestined …
Although some very well established reactions  called  prabha karma are difficult to change…but by devotional service, they  are  also eradicated …the Gaudia vaisnava.acaryas say , particularly the service of chanting in love and devotion the names of Divinity.
Ultimately devotees don’t say..

“When’s my karma gonna change..”

They get on with their devotional lives, and are absorbed in trying to cultivate a spiritual body and spiritual attitudes, their interests are in a forward direction and in pleasing Radharani and Krishnas devotees ,and with cultivation of a spiritual identity,  , they don’t care for and are unaffected by any trivial effects of either good or bad karma ,
