In Jainism, purifying thoughts means reducing rāga-dveṣa — attachment and hatred — and cultivating śuddha bhāva (pure inner state). The main methods are:

1. Practice Ahimsa in mind

- Avoid angry, cruel, jealous, or harmful thoughts. - Wish well for all living beings.

1. Control the mind through self-restraint

- Be aware of what you think. - Stop negative imagination, blame, pride, and greed early.

1. Meditation and आत्म-चिंतन

- Sit in शांत bhāva and observe the mind. - Reflect: “Is this thought increasing bondage or freedom?”

1. Samayik

- In Jain practice, Samayik helps calm the mind and bring equanimity. - It is a strong method for inner purification.

1. Pratikraman

- Repent for wrong thoughts, words, and actions. - Resolve not to repeat them.

1. Swadhyaya

- Study Jain scriptures and teachings. - Right knowledge helps purify thinking.

1. Maitri, Pramod, Karuna, Madhyasth

- Friendship toward all beings - Respect for the virtuous - Compassion for the suffering - Neutrality toward the wicked without hatred

1. Reduce attachment

- Less greed, ego, possessiveness, and desire. - This is very important for mental purity in Jainism.

1. Follow the Three Jewels

- Right Faith - Right Knowledge - Right Conduct These guide the mind toward purity and liberation.

1. Live with awareness

- Every thought creates karmic bondage or purity. - Choose thoughts of peace, forgiveness, and detachment.

A simple Jain way to remember it is: “Purify the mind by reducing passions and increasing equanimity.”

If you want, I can also give this in a very short daily practice format.
