Ramakrishna and Narendranath

During 1855 to 1866, these twelve years, Ramakrishna undergone rigorous religious practices and followed by six years of in getting acquainted with his own power and the spiritual state of the people  in general. Thereafter he was seen engaged with unrivalled energy in the task of reestablishing the eternal religion and arresting the decline of religion that came on India under the strong impulse of Western ideas and ideals which preached that this world was all in all. He disappeared from the scene of this world after finishing this part of his work. 
In 1984, when Narendranath was reading B.A., Ramkrishna wanted to make him understand two things;
1. Faith on God, and
2 Faith on religious activities.
Narendranath had the privilege of enjoying the holy company of Ramakrishna for five years, from 1881 to 1886. He used to come from home and pay visits to him during those days.
Narendranath had the privilege of enjoining the holy company of Ramakrishna for five years, from 1881 to 1886.Like all the other devotees of Calcutta, he also used to come from home and pay visits to Ramakrishna during those days.
If Narendra failed to come to Dakshineswar, Ramakrishna  became restless to see him and would send one to bring him.
Just as Narendra saw Ramkrishna's purity renunciation and single minded devotion and became attracted to him since his first meeting, Ramakrishna too was charmed to see his boundless self-confidence and love of truth and made him his own from the first day they meet.
Ramakrishna understood that Narendra was a highly qualified person in the domain in the domain of spirituality and tried to infuse into him the belief in the truth of non-dualism from the very first day he met him.   
Narendra, first of all, applied his intellect to ascertain whether there is any possibility of error in the words of the scriptures and of the teacher, and began practising them only when he regarded them as standing the test of reason. Although possessed of a firm faith in the existence of   God owing to past impressions. Narendra all through his life entertained, the idea that all men, without an exception, are liable to errors and superstitions; there is no reason why one should accept indiscriminately any word of any human being.
