Vakula Devi is Sri Venkateswara’s adoptive mother. In the past, Yasoda Devi raised Sri Vishnu in the incarnated form of Sri Krishna and, not completely satisfied to see his presence, wished him to continue for some time. He granted her wish in a blessing saying that in another incarnation he would fulfill her wish. In accordance with this boon, Sri Maha Vishnu in the form of Sri Srinivasa now made her happy. Yashoda Devi, born as Vakulamata, enjoyed his presence while serving him.
