I had heard that gaudiyas believe that a person loses varna after diksha(and that, in some parivaras, dvijas are supposed to throw away their janeu). Is this true?
Also some shaktas claim that after purnabhishek, varna is sacrificed.
The followers of Srila Bhaktivinode and Srila Bhaktisiddhanta Sarasvati of the Gaudiya Vaishnava Sampradaya retain the Yajnopavita from the stage of Brahmacharya all the way up to Sanyasa for the same reasons as stated here.
Like any library, Hinduism Stack Exchange shares great information, but does not offer personalized advice, and does not take the place of seeking such advice from any Acharya, Pundit, astrologer, Guru or other trustworthy Counselor.
