Krsnadasa Kaviraja Gosvami has composed this Sanskrit verse for the beginning of his book, and now he will explain it in detail. He offers his respectful obeisances to the six principles of the Absolute Truth. Gurun is plural in number because anyone who gives spiritual instructions based on the revealed scriptures is accepted as a spiritual master. Although others give help in showing the way to beginners, the guru who first initiates one with the maha-mantra is to be known as the initiator, and the saints who give instructions for progressive advancement in Krsna consciousness are called instructing spiritual masters. The initiating and instructing spiritual masters are equal and identical manifestations of Krsna, although they have different dealings. Their function is to guide the conditioned souls back home, back to Godhead. Therefore Krsnadasa Kaviraja Gosvami accepted Nityananda Prabhu and the six Gosvamis in the category of guru.
