Kali Bein is a rivulet in Punjab, India that flows into the confluence of the rivers Beas and Satluj at Harike. Guru Nanak attained enlightenment after taking a bath in the Kali Bein, and despite its religious history in Sikhism, the rivulet is not considered holy by the Sikhs in Punjab, as no bodies of water are considered holy in Sikhism aside from the Sikh Sarovars of Gurdwaras.
