In Jainism, the main question is not “Is this legal?” but “Does this increase himsā (violence), attachment, or others’ vices?”

Gambling (dyūta) is counted among the sapta vyasan (seven vices) and is clearly discouraged for householders in Jain texts. It leads to:

• Greed and addiction
• Financial and mental harm to families
• Dishonesty and deceitful tendencies ( jainknowledge.com)

So, actively helping a gambling business grow (through strategy, contracts, expansion, defence etc.) usually means:

1. Prayashchitta dravya-himsā (indirect violence)

You are not gambling yourself, but your skills help more people get trapped in that vice. That becomes sahāyaka himsā (supporting harm).

1. Problem of right livelihood (samyak ājīva)

Jain ethics say we should avoid earning from trades that promote addictions & moral downfall (like intoxicants, etc.). Gambling falls very close to that category in spirit. ( jainknowledge.com)

1. Karmic view

From a Jain standpoint, you earn not only money but also share in the karmic result of what your work enables. Even if your intention was “just professional,” the upādāna–nimitta link (active helper) still exists.

So is it “against Jainism”?

• Strictly speaking: Yes, helping a gambling company expand goes against the ideals of samyak ājīva and supporting others away from vice, not into it.
• But: Jainism is also very realistic about gradual change. As a layperson, you may have done this without full understanding. The important part is what you do now, having more clarity.

What you can do now

If you feel uneasy (which is why you asked), you’re already moving toward samyak darshan (right outlook). Some practical Jain responses:

1. Stop further involvement if possible

- Avoid taking new work that directly helps gambling, casinos, betting apps, etc. - If you must work there for a short time (financial compulsion), consciously plan an exit.

1. Internal correction (bhāva)

- Admit to yourself: “This line of work does not align with ahimsa and right livelihood.” - Develop pratikraman-bhāva (repentance mindset): - Mentally accept: “Whatever harm was supported through me, I regret it and do not wish to repeat it.”

1. Pratikraman / Prāyaścitta

According to your tradition (Digambar/Śvetāmbara), you can: - Include this specifically in your daily or periodic pratikraman: - Recall the activity, - Feel sincere remorse, - Take a small anushthan (self-vow) like, “I will not assist in new gambling expansions now onwards, as far as it is in my control.” - If you have a guru/pravachan-kār you trust, you may seek personal prāyaścitta guidance.

1. Positively redirect your skills

- Consciously choose clients and sectors that are ethically safer and closer to Jain ideals: e.g. education, healthcare (non-violent), technology, simple trade with minimal harm, etc. ( jainknowledge.com) - Use part of the income already earned for dāna (charity) and support of genuinely good causes, with a feeling of inner cleansing, not as “payment” but as parivartan (change of direction).

1. Avoid harsh self-guilt, keep clear responsibility

- Jain dharma is strict about ethics but also compassionate about progressive refinement. - Acknowledge: “Yes, from the angle of Jain dharma this was not right livelihood.” - Then focus more on what right step you take next rather than getting stuck in self-hate, which again binds karma.

In short: Yes, representing and expanding a gambling company does conflict with Jain principles. You can now turn this awareness into a step forward—reduce and stop such work, do sincere pratikraman, and slowly align your profession more closely with ahimsa and samyak ājīva.
