The Pranpratisthit Murtis are precise Are living Murties and bestow the devotee with longevity, safety versus sudden incidents and thefts. मन्त्र ज्यो शत्रु भयो। डाकिनी वायो, जानु वायो। The repetitive nature of chanting Bija Mantras can assist to concentration the mind and convey it into a condition of deep concentration. https://www.youtube.com/@Mahavidyabaglamukhi
