Srila Visvanatha Cakravarti comments as follows on this verse: “It is stated here that Citralekha resorted to mystic power (yogam asthita). As explained in the Hari-vamsa and other literatures, she needed to employ her powers because when she arrived at Dvaraka she found herself unable to enter Lord Krsna’s city. At that time Sri Narada Muni instructed her in the mystic art of entering. Some authorities also say that Citralekha is herself an expansion of Yoga-maya.”
