In Jain Dharma, Antaraya karma is the karma that creates obstacles in charity, gain, enjoyment, and spiritual effort.

To weaken and overcome it, one should practice:

• Ahimsa: avoid harm in thought, speech, and action.
• Satya: remain truthful.
• Aparigraha: reduce attachment and greed.
• Dana: give with a pure and selfless heart.
• Seva: serve saints, the needy, and the Sangh.
• Swadhyaya: study Jain scriptures regularly.
• Tap: do penance such as fasting, ekasana, ayambil, and other suitable austerities.
• Samayik and Pratikraman: purify the soul through reflection and repentance.
• Bhakti and Namaskar: worship the Arihants, Siddhas, Acharyas, Upadhyayas, and Sadhus with devotion.
• Control of anger, pride, deceit, and greed: these greatly support karmic bondage.

The key is to live with purity of intention, non-attachment, and steady spiritual discipline. Antaraya karma is reduced by selfless conduct, charity, restraint, and sincere tapasya.

If you meant Antaraya karma, this is the Jain way to overcome it.
