Don’t mistake lack of qualification as sectarian discrimination
The Vedas… are specifically meant for persons who have acquired the brahminical qualifications. This restriction is based not upon any sectarian distinction but upon qualification. The Vedic literatures cannot be understood unless one has developed the brahminical qualifications. It is regrettable, therefore, that persons who have no brahminical qualifications and have never been trained under a bona fide spiritual master nevertheless comment on Vedic literatures like the Srimad-Bhagavatam and other puranas, for such persons cannot deliver their real message.
