Parshvanath (Parsvanath) is the 23rd Tirthankara in Jainism. Key points:

• He is revered as a great teacher who attained kevala jnana (omniscience) and then taught to others.
• His emblem is the serpent with a hood, and his usual symbol in art is the hooded cobra.
• In Jain tradition, his life story is narrated in canonical texts such as the Kalpa-sutra and related Jain chronicles. Different Jain sects (Digambara and Śvetāmbara) may have slightly different details in their legends, but the core teaching remains the same: a path of non-violence, truth, and spiritual discipline.
• Historically, Parshvanath is regarded as a historical seed for the Jain sangha, with temples and iconography celebrated across Jain communities.
