Udasi is a separate sect in Sikhism. The members of this sect follow an ascetic life, preaching the Sikh religion. They are also well versed in the basics of
Hinduism and the principles of the
Vedas. This sect was founded by Baba Sri Chand, the son of Guru Nanak.
Baba Sri Chand was a great devotee of his father, who was the founder of the Sikh religion. His utter devotion towards the guru led to the establishment of this ascetic order. This sect was responsible for keeping alive the Sikh religion during its turbulent years, when numerous Sikh warriors were hunted down during the religious persecution of the Mughals.
The Udasis usually wear ochre colored robes or simply a loin cloth. They smear their body with ashes. They spend their lives in prayer and meditation. They generally do not form marital alliances. Their religious life style is supported by their knowledge in the Sanskrit language and the Vedas.
