Brahmana: Definition of a Brahmana

                                                                  Q. In many places in the Srimad Bhagavatam and in other scriptures the word "brahmana" is mentioned but not Vaishnava. Lord Sri Krishna also addresses as brahmanas & even it is said Om Namo Brahmanya Devaya. So this is my question: why does Lord Krishna refer to Brahmanas but not Vaishnavas?

                                                                  The Supreme Lord very much favors brahminical culture because it is the basis of progress in human society.

                                                                  Progressive human civilization is based on brahminical culture, God consciousness and protection of cows. Simply by properly respecting and protecting genuine brahmanas and the cows, human society can become perfectly prosperous and progressive.
