Great Swami Vivekananda, as Ramakrishna (His Guru) has said, was not an ordinary man, but a nityasiddha, perfect even before birth, an Isvarakoti, or special messenger of God born on earth to fulfil a divine mission. Vivekananda was encouraged by J.H. Wright, a professor of Greek at Harvard University, to represent Hinduism in the 1893 World Parliament of Religions in Chicago. When he expressed reservations saying he had no credentials, the professor replied, "To ask you, Swami, for your credentials is like asking the sun about its right to shine." He wrote about Vivekananda to the chairman of the committee on selection of delegates, "Here is a man more learned than all our learned professors put together." Absorbed, one day, in samadhi, Ramakrishna (Vivekananda's Guru) had found that his mind was soaring high, going beyond the physical universe of the sun, moon, and stars, and passing into the subtle region of ideas. As it continued to ascend, the forms of gods and goddesses were left behind, and it crossed the luminous barrier separating the phenomenal universe from the Absolute, entering finally the transcendental realm. There Ramakrishna saw seven venerable sages absorbed in meditation. These, he thought, must have surpassed even the gods and goddesses in wisdom and holiness, and as he was admiring their unique spirituality he saw a portion of the undifferentiated Absolute become congealed, as it were, and take the form of a Divine Child. Gently clasping the neck of one of the sages with His soft arms, the Child whispered something in his ear, and at this magic touch the sage awoke from meditation. He fixed his half-open eyes upon the wondrous Child, who said in great joy: 'I am going down to earth. Won't you come with me?' With a benign look the sage expressed assent and returned into deep spiritual ecstasy. Ramakrishna was amazed to observe that a tiny portion of the sage, however, descended to earth, taking the form of light, which struck the house in Calcutta where Narendra's family lived, and when he saw Narendra for the first time, he at once recognized him as the incarnation of the sage. He also admitted that the Divine Child who brought about the descent of the rishi was none other than himself.
