Bhīṣma said: “Those who are born from an āsura form of marriage tend to be fault-finders, deeply unrighteous, appropriators of others’ wealth, deceitful, and inclined to conduct that runs contrary to dharma.”
भीष्म उवाच
Bhīṣma links the manner of marriage to ethical disposition, warning that coercive or acquisitive unions (āsura-vivāha) foster tendencies like envy, deceit, theft, and conduct opposed to dharma.
In his instruction on dharma, Bhīṣma is describing the moral consequences associated with different forms of marriage, here characterizing the offspring said to arise from the āsura type.
