What happens in moksha
In Jainism, moksha is the state of ultimate liberation and freedom from the cycle of birth and death (samsara). When a soul attains moksha, it is completely freed from all karmic bondage. This means that all karmas—both good and bad—that bind the soul to the cycle of reincarnation are destroyed.
Upon attaining moksha, the soul rises to the Siddhashila, which is the highest realm at the top of the universe. Here, the liberated soul (Siddha) exists in its purest form, characterized by infinite knowledge (keval jnana), infinite perception (keval darshan), infinite bliss (anant sukh), and infinite energy (anant virya). The soul no longer experiences any suffering, pain, or rebirth. It remains in a state of eternal bliss and consciousness.
In summary, in Jainism, moksha is the ultimate goal, representing the soul's liberation from all karmic bondage and eternal existence in a state of infinite knowledge and bliss.
