I guess you don't believe in soul contracts. Fate (elements of soul contracts) + free will = destiny. But you are not all off about vibrations being part of fate.

"Karma is a vibrational level that draws the experiences needed for healing and growth to a soul. Nothing more....I realized after reading DL’s guides’ thoughts on karma that the law of attraction describes the vibrational pulls of our soul contracts, not what we humans consciously or subconsciously emit." https://medium.com/channspirations/revisiting-karma-and-the-law-of-attraction-997965601b65
