Other important thinkers
The Sikh Gurus undoubtedly were very important in propounding the tenets of Sikhism. Thomas, one of the twelve disciples of Jesus, is believed to have preached and finally died in India. Saint Francis Xavier also developed a Jesuit missionary method that left a significant impression upon the missionary history of India.

Jesus of Nazareth may have had spiritual training or influences from South Asian spiritual thought. A school of thought believes Jesus escaped the Roman empire to Kashmir.
