I think gambling falls under greed?
You can debate, but I feel these are mixed with - lust is basically the reason to gain money is wanting power.
and I thought being a buddahist is more of a lifestyle then a religion.
I would have to disagree that gambling falls under greed. It depends on why you play whether or not this falls under greed. If you play like I do, for fun and I do not care if I win or loose, then I do not see an issue with this. When you are not playing for tthe fun of playing, then I can see in some cultures, why it would be considered a sin/crime.
