In Jainism, Bimbisara is known as King Shrenik (Shrenik Raja).

Short, clear points:

• He was the king of Magadh (Magadha) with capital Rajgriha (Rajgir).
• He lived in the time of Bhagwan Mahavir (24th Tirthankar) and became his devoted Shravak (lay follower).
• In Jain scriptures like Bhagavati Sutra, Uttaradhyayan Sutra, etc., he is mentioned many times asking deep questions about karma, rebirth, and moksha to Bhagwan Mahavir.
• He gave strong support and protection to the Jain Sangh, so he is remembered as an important Jain king.
• Due to some heavy past karmas, Jain texts say that after that life he went to Narak (hell), but in the next time-cycle he will become a Tirthankar (future great spiritual teacher).
• In many Jain traditions, he is respected as a great but not yet liberated soul, a powerful example of how even a king can have deep shraddha (faith) in Jain Dharma.
