The word 'Udasi' is derived from the Sanskrit word which means "one who is indifferent to or disregardful of worldly attachments, a stoic, or a mendicant." In Sikh tradition, the term udasi has also been used for each of the four preaching tours of Guru Nanak Sahib Ji; in this sense, udasi meant a prolonged absence from home. Some scholars, including many Udasis, trace the origin of the sect back to the Puraṇic age, but, historically speaking, Baba Sri Chand was the founder.
