Matsya, the Lord's Fish Incarnation

of the living being, who is part of the  sac-cid-ānanda-vigraha , is the luster of  ānanda , or pleasure.  Ānandamayo 'bhyāsāt . Every living entity has the right to become  ānandamaya , joyful, because he is part of the  sac-cid-ānanda-vigraha , Kṛṣṇa. 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  svarūpa , 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 guruḥ , the spiritual master of all other spiritual masters.
Even though we may not have the fortune to contact the Supreme Lord personally, the Lord's 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. Śrī Caitanya Mahāprabhu therefore gives a definition of  guru .  Yāre dekha, tāre kaha 'kṛṣṇa'-upadeśa : the bona fide  guru  is he who advises his disciples exactly in accordance with the principles spoken by Kṛṣṇa. The bona fide  guru  is he who has accepted Kṛṣṇa as  guru . This is the  guru-paramparā  system. The original  guru  is Vyāsadeva because he is the speaker of  Bhagavad-gītā  and  Śrīmad-Bhāgavatam , wherein everything spoken relates to Kṛṣṇa. Therefore  guru-pūjā  is known as Vyāsa-pūjā. In the final analysis, the original  guru  is Kṛṣṇa. His disciple is Nārada, whose disciple is Vyāsa, and in this way we gradually come in touch with the  guru-paramparā . One cannot become a  guru  if he does not know what the Personality of Godhead Kṛṣṇa or His incarnation wants. The mission of the  guru  is the mission of the Supreme Personality of Godhead: to spread Kṛṣṇa consciousness all over the world.
