Birth and childhood

Vivekananda was born Narendranath Datta (shortened to Narendra or Naren) in a Bengali Kayastha family at his ancestral home at 3 Gourmohan Mukherjee Street in Calcutta, the capital of British India, on 12 January 1863 during the Makar Sankranti festival. He belonged to a traditional family and was one of nine siblings. His father, Vishwanath Datta, was an attorney at the Calcutta High Court. Durgacharan Datta, Narendra's grandfather was a Sanskrit and Persian scholar who left his family and became a monk at age twenty-five. His mother, Bhubaneswari Devi, was a devout housewife. The progressive, rational attitude of Narendra's father and the religious temperament of his mother helped shape his thinking and personality.

Narendranath was interested in spirituality from a young age and used to meditate before the images of deities such as Shiva, Rama, Sita, and Mahavir Hanuman. He was fascinated by wandering ascetics and monks. Naren was naughty and restless as a child, and his parents often had difficulty controlling him. His mother said, "I prayed to Shiva for a son and he has sent me one of his ghosts".

In 1871, at the age of eight, Narendranath enrolled at Ishwar Chandra Vidyasagar's Metropolitan Institution, where he went to school until his family moved to Raipur in 1877. In 1879, after his family's return to Calcutta, he was the only student to receive first-division marks in the Presidency College entrance examination. He was an avid reader in a wide range of subjects, including philosophy, religion, history, social science, art and literature. He was also interested in Hindu scriptures, including the Vedas, the Upanishads, the Bhagavad Gita, the Ramayana, the Mahabharata and the Puranas. Narendra was trained in Indian classical music, and regularly participated in physical exercise, sports and organised activities. Narendra studied Western logic, Western philosophy and European history at the General Assembly's Institution (now known as the Scottish Church College). In 1881 he passed the Fine Arts examination, and completed a Bachelor of Arts degree in 1884. Narendra studied the works of David Hume, Immanuel Kant, Johann Gottlieb Fichte, Baruch Spinoza, Georg W. F. Hegel, Arthur Schopenhauer, Auguste Comte, John Stuart Mill and Charles Darwin. He became fascinated with the evolutionism of Herbert Spencer and corresponded with him, translating Spencer's book Education (1861) into Bengali. While studying Western philosophers, he also learned Sanskrit scriptures and Bengali literature. William Hastie (principal of General Assembly's Institution) wrote, "Narendra is really a genius. I have travelled far and wide but I have never come across a lad of his talents and possibilities, even in German universities, among philosophical students." Some accounts have called Narendra a shrutidhara (a person with a prodigious memory).

Spiritual apprenticeship - influence of Brahmo Samaj

In 1880 Narendra joined Keshab Chandra Sen's Nava Vidhan, which was established by Sen after meeting Ramakrishna and reconverting from Christianity to Hinduism. Narendra became a member of a Freemasonry lodge "at some point before 1884" and of the Sadharan Brahmo Samaj in his twenties, a breakaway faction of the Brahmo Samaj led by Keshab Chandra Sen and Debendranath Tagore. From 1881 to 1884 he was also active in Sen's Band of Hope, which tried to discourage youths from smoking and drinking.

It was in this cultic milieu that Narendra became acquainted with Western esotericism. His initial beliefs were shaped by Brahmo concepts, which included belief in a formless God and the deprecation of idolatry, and a "streamlined, rationalized, monotheistic theology strongly coloured by a selective and modernistic reading of the Upanisads and of the Vedanta." Rammohan Roy, the founder of the Brahmo Samaj who was strongly influenced by unitarianism, strived toward an universalistic interpretation of Hinduism. His ideas were "altered considerably" by Debendranath Tagore, who had a romantic approach to the development of these new doctrines, and questioned central Hindu beliefs like reincarnation and karma, and rejected the authority of the Vedas. Tagore also brought this "neo-Hinduism" closer in line with western esotericism, a development which was furthered by Keshubchandra Sen. Sen was influenced by transcendentalism, an American philosophical-religious movement strongly connected with unitarianism, which emphasised personal religious experience over mere reasoning and theology. Sen strived to "an accessible, non-renunciatory, everyman type of spirituality", introducing "lay systems of spiritual practice" which can be regarded as prototypes of the kind of Yoga-exercises which Vivekananda popularised in the west.

The same search for direct intuition and understanding can be seen with Vivekananda. Not satisfied with his knowledge of philosophy, Narendra came to "the question which marked the real beginning of his intellectual quest for God." He asked several prominent Calcutta residents if they had come "face to face with God", but none of their answers satisfied him. At this time, Narendra met Debendranath Tagore (the leader of Brahmo Samaj) and asked if he had seen God. Instead of answering his question, Tagore said "My boy, you have the <
