Followers of Mata Vaishno Devi believe that no one can visit her temple unless and until she issues a "bulawa" to them, that is, till she calls them to visit her shrine. Irrespective of caste, creed and social status, it is said that a journey to the sacred shrine of Vaishno Devi can materialize if and only if she wills it and blesses the devotee with her darshan. In fact, many devotees have been said to experience this first hand. The converse is also said to be true. If there is a Call from the Deity, even those who had not planned for the trip are bound to go visit the Mother at her shrine.
Those desirous of visiting her shrine, therefore, make a fervent wish in their hearts and pray to her for showering her grace and granting darshan to them. Then, they surrender to her will and leave it to her to decide when it would be the right time for them to go visit her Holy Abode.
