After his upanayan (coming-of-age) rite at age eleven, Tagore and his father left Calcutta in February 1873 to tour India for several months, visiting his father’s Santiniketan estate and Amritsar before reaching the Himalayan hill station of Dalhousie. There Tagore read biographies, studied history, astronomy, modern science, and Sanskrit, and examined the classical poetry of Kālidāsa.
During his 1 month stay at Amritsar in 1873 he was greatly influenced by melodious gurbani and nanak bani being sung at Golden Temple for which both father and son were regular visitors. He mentions about this in his ‘MY REMINISCENCES (1912)
The golden temple of Amritsar comes back to me like a dream. Many a morning have I accompanied my father to this Gurudarbar of the Sikhs in the middle of the lake. There the sacred chanting resounds continually. My father, seated amidst the throng of worshippers, would sometimes add his voice to the hymn of praise, and finding a stranger joining in their devotions they would wax enthusiastically cordial, and we would return loaded with the sanctified offerings of sugar crystals and other sweets.
He wrote 6 poems relating to Sikhism and no. of articles in Bengali child magazine about Sikhism.
