Appearance of Gangamata Gosvamini
Gangamata Goswamini was the daughter of King Naresha Narayana of Bengal. From childhood she showed deep devotion to Krishna. Refusing to marry and renouncing her kingdom, she went in search of a bona fide guru. In Vrindavan she accepted Haridasa Pandita as her guru and took instructions from him. Performing severe austerities, she wore only rags and begged food door to door. On her guru's order, she went to Jagannatha Puri, where she became a great preacher and guru. Hundreds of people attended her discourses on Srimad-Bhagavatam, and many people, including brahmanas, Lord Jagannatha's priests, and even the king, accepted her as their spiritual master.
