Aneka Koti Namaskaram to both Swamies
Just conveying what Adiyen read in a book today from authenticated source. Conveying without any edition in what is written.
“When the upasaka wants to begin Bakthi yoga, there are many sins of his that stands in his way. He will have to settle accounts with them either by experiencing the fruits of all those sins standing to his credit or by making suitable acts of expiation (Prayascitta) for every one of them. The sins are so many in number that all the time in the future will not be enough either for experiencing the fruits or for performing acts of expiation. Then how to get over the sins and begin the Bakthi yoga? The Sastras prescribe Prapatti (surrender or the means of seeking refuge under Parabrahmam) as the sure way of getting rid of the sins.
The yogi falls at the feet of Paramatma, expressing his incompetency and destitution and prays Him to destroy his sins and help him to begin the Bakthi yoga. Baghavan in His infinite mercy, takes the yogi under His protection and destroys the sins. When the sins that stand in the way of beginning the Bakthi-yoga has thus been wiped out, the yogi is able to begin the practise of Bakthi yoga or Upasana.”

So, as per author, Bakthi yoga and Prapatti are not two different paths and they go hand in hand. He says, in fact, Prapatti is the starting point of Bakthi yoga. There is nothing here as my opinion. Just conveyed what Adiyen read as such.
Bagavad Ramanujar also says, absolution of fruits of karma is achieved by surrender.
