Here is a simple Jain view on vedan (sensation) and nirjara (shedding of karmic particles) as they relate to the Tejas body (the subtle luminous body that accompanies the soul after shedding gross karma).

• What is Tejas?

- Tejas is the subtle, luminous aspect of the soul’s own body. It is not a physical matter but a refined, karmic-energy-related sheath that grows clearer and brighter as karmic bondage decreases.

• Vedan (sensations) and Tejas

- When the soul comes into contact with the physical world through senses, it experiences vedan—pleasure, pain, or neutral feelings. - These sensations are not permanent; they arise due to current karma and past karmas that tint the soul’s experience. - In the context of Tejas, vedan reflects how the subtle body perceives and is affected by contact and impressions. Greater bondage of karma tends to color vedan more strongly, while purifying practices reduce these vivid sensations.

• Nirjara (shedding of karmas) and Tejas

- Nirjara is the process by which karmic particles attached to the soul are shed or worn away. This happens through disciplined conduct (non-violence, truth, celibacy, non-possessiveness), penance, self-control, and right knowledge and faith. - As karmas are shed (nirjara), the residues that give rise to vedan diminish. The Tejas body becomes purer and brighter because fewer karmic particles are weighing on the soul. - In practical terms, sustained tapas (austerities), proper ethical conduct, and contemplation reduce painful or distracting vedan and gradually clear the Tejas veil.

• Digambar vs. Shwetambar nuance

- Both traditions agree on the basic mechanism: vedan arises from sense-contact and karmic bondage; nirjara reduces karmic bondage, which in turn makes the Tejas body brighter and purer. - Specific textual interpretations of Tejas, vedan, and nirjara can vary in emphasis between Digambar and Shwetambar expositions, but the core ideas remain aligned: purify the soul, diminish sensations caused by karma, and brighten the subtle Tejas.

• Key takeaway

- Vedan is the experiential aspect that accompanies sense-contact (and karmic bondage) in the soul. - Nirjara is the practical process of shedding karmic particles to lessen vedan. - Together, they explain how the Tejas body becomes purer and more radiant as one progresses on the spiritual path.

If you’d like, I can share a simple sutra-stotra reference in Jain scriptures that mentions the Tejas body and related concepts, or explain how these ideas fit into a particular Jain text (Digambara or Śvetāmbara) in more detail.
