The word varnam refers to the luster of ones original identity. The original luster of gold or silver is brilliant. Similarly, the original luster of the living being, who is part of the sac-cid-ananda-vigraha [Bs. 5.1], is the luster of ananda, or pleasure. Anandamayo bhyasat. Every living entity has the right to become anandamaya, joyful, because he is part of the sac-cid-ananda-vigraha [Bs. 5.1], Krsna. Why should the living being be put into tribulation because of dirty contamination by the material modes of nature? The living entity should become purified and regain his svarupa, his original identity. This he can do only by devotional service. Therefore, one should adopt the instructions of the Supreme Personality of Godhead, who is described here as guror guruh, the spiritual master of all other spiritual masters.

Even though we may not have the fortune to contact the Supreme Lord personally, the Lords representative is as good as the Lord Himself because such a representative does not say anything unless it is spoken by the Supreme Personality of Godhead. Sri Caitanya Mahaprabhu therefore gives a definition of guru. Yare dekha, tare kaha krsna-upadesa: [Cc. Madhya 7.128] the bona fide guru is he who advises his disciples exactly in accordance with the principles spoken by Krsna. The bona fide guru is he who has accepted Krsna as guru. This is the guru-parampara system. The original guru is Vyasadeva because he is the speaker of Bhagavad-gita and Srimad-Bhagavatam, wherein everything spoken relates to Krsna. Therefore guru-puja is known as Vyasa-puja. In the final analysis, the original guru is Krsna, His disciple is Narada, whose disciple is Vyasa, and in this way we gradually come in touch with the guru-parampara. One cannot become a guru if he does not know what the Personality of Godhead Krsna or His incarnation wants. The mission of the guru is the mission of the Supreme Personality of Godhead: to spread Krsna consciousness all over the world.
