In Jainism, achieving moksha (liberation) is the ultimate goal and signifies the soul's release from the cycle of birth and death (samsara). To attain moksha in fewer births, Jain teachings emphasize the following key principles and practices:

1. Right Faith (Samyak Darshan): Develop true understanding and unwavering faith in the teachings of the Tirthankaras, the nature of the soul, karma, and reality.

1. Right Knowledge (Samyak Jnan): Study and understand Jain scriptures, doctrines, and the true nature of the soul and karma.

1. Right Conduct (Samyak Charitra): Live a life of ethical conduct, following the five main vows (for householders: anuvratas; for monks: mahavratas):

- Ahimsa (non-violence) - Satya (truthfulness) - Asteya (non-stealing) - Brahmacharya (chastity) - Aparigraha (non-possessiveness)

1. Self-Discipline and Austerity (Tapasya): Practice self-restraint, fasting, meditation, and other forms of spiritual discipline to reduce and eliminate karmic bondage.

1. Minimize New Karmas and Shed Old Karmas: Avoid actions that attract new karmas (asrava) and engage in activities that help shed existing karmas (nirjara), such as repentance, confession, and spiritual practices.

1. Association with the Virtuous (Sadhu-Sangh): Spend time with spiritually advanced individuals and monks to gain inspiration and guidance.

1. Intense Desire for Liberation: Cultivate a strong and sincere desire for moksha, making it the central aim of life.

By sincerely following these steps with devotion and discipline, a soul can speed up its spiritual progress, reduce the number of births, and ultimately achieve moksha sooner. However, Jainism also teaches that the fruition of karma and spiritual progress depend on both current efforts and past karmic conditions. Thus, patience, persistence, and unwavering commitment to the path are essential.
