Revan Nath (also known as Revanasiddha) is the Great saint from whom this everlasting Guruparampara began.He was one of the nine great saints who were known as NAVANATH(Nine sages). He was the Noble follower & a Great Devotee of Shree Datta (Shree Datta is Considered as One of the Gods in Indian Religion ) .A woman called, as “maiee” ,for some reason, was against all saints in “karver” province. She used to trouble the saints who had acquired Siddhi (God gifted powers) and hence Revananath was requested by his disciple (Marul Siddha) to stop Maiee by using powers given to Revananath by Shree Datta. Revananath accepted this request & converted “maiee” to a musical instrument, which is said that, he used to play until his death. Due to his very kind heart & Great powers with which he stopped “maiee”, people started to call him Kada Siddha. The temple of Kada Siddha is located on a hill Siddhagiri near Karver Province. People believed & worshiped Kada Siddha to be Lord Shankar (the Great Hindu God, believed to be residing on the Kailash Mountain in the Great HIMALAYAS).

A Marathi book, Navanath Bhaktisar (Published in 1819) by Malukavi contains life sketch of Revananath. In the three chapters (34th, 35th and 36th) of this book, one can see the descriptions about this story. Chamasnarayana -one among Navanarayanas for the sake of welfare of the world incarnated near Revateer and grew up in the faunily of an ordinary farmer. One day while engaged in agricultural work he had the vision of Sri Dattatraya and by his grace he attained ‘Mahima’ Siddhi (occult power). On the basis of which he had performed several miracles. Therefore he became famous as ‘Revanasiddha’ in that region. After sometime Machindaranath paid a visit to that region. Owing to the occult power tiger, lion and other such wild animals forgetting their enemities were found to be with Machindaranath. On seeing this, Revananath was flabbergasted. Revananath realized that Mahimasiddhi that he had attained was not of any help. This could be accomplished only by God realization (Brahmajnana). According to his wish Machindaranath took Revananath to Sri Dattatraya. Sri Dattatraya initiated Revananath into spiritual life smd Revananath spent sometime in penance under the guidance of Sri Dattatraya and Revananath realized God and then Revananath went to Mogalayi, Kanchi, Balehalli and other places. After that for sometime he lived in Vite-Renavi (Renagiri) of Mandesh.

In another version, Some chapters related to the story of Revanasiddha are found in the Marathi work ‘Siddhanta Sar’. This work was composed in the year 1713 A. D. (1635 sake) at Kiamte-on the bank of the river Krishna in Vairatdesh. Maharashtra Saraswatas opine that this work has been written by Kesarinath who was in the line of Machindaranath. Revanasiddha incarnated from the phallic (Linga) of Someshwara. His disciple was Marulasiddha and Ekoram was the disciple of Marulasiddha. Thus ?? the tradition of Siddhas began from Revananath according to this work. There was a woman called ‘Mayi’ in the region of Karaveer who used to scare and capture Siddhas by challenging them to drink poison which was with her. At the instance of Marulasiddha, Revanasiddha drank all the poison and hence Mayi was defeated and surrendered to Revanasiddha. Revanasiddha initiated Mayi and released all the Siddhas. This story is found in many other works. Regarding this Revanasiddha’s time there are different versions (i) The phallic of Chandramouleswara was handed over to Adi Shankaracharya by Revanasiddha only and therefore Revanasiddha must be regarded as a contemporary of Adi Shankaracharya. (ii) But R. B. Halakatti in his ‘Amaraganadhiswara charitregalu (P.70) indicates that Revanasiddha lived during the life time of Bijjal (1157 A. D.-1168 A. D.). The palace of Bijjal began burning when Bijjal became arrogant and put boiling rice in the ‘Jolige’ (a kind of shoulder bag) and the fire got extinguished only when the king Bijjal begged the pardon of Revanasiddha.

The saint of Nimbargi (Sadguru Shri Nimbargi Maharaj) had his initiation from a saint
called Muppinmuni, who lived about the year 1810 in Siddhagiri,
and who was in the Kadasiddha line.
