Why are greed and attachment called the root of sin?
Greed and attachment lead to wrong action
Greed and attachment (moh) are the root cause of sin, because a person harms others for his own good. Both are dangerous things.
To benefit himself a person harms others, and to increase his wealth excessively he also does wrong. So greed and attachment are both dangerous things.
