As Rishabdev was one of the first lord in jainsim, who did he follow?
In Jainism, Rishabhanatha (also called Adinath) is regarded as the first Tirthankar of the current cosmic half-cycle. He did not follow anyone; he is considered the one who established the dharma and taught the path to liberation to all beings. After attaining kevala jnana (supreme knowledge), he preached the Jain path and laid the foundation for the moral and spiritual code that later followers practiced.
Note: In both Digambara and Śvetāmbara traditions, he is honored as the first Tirthankar, though there are variations in legends and details about his life.
