Aggressors - Based on Bhagavad Gita

(Reference: Bhagavad Gita- As it is)

According to Vedic injunctions there are six kinds of aggressors:

· A poison giver

· One who set fire to house

· One who attack with deadly weapons

· One who plunders riches

· One who occupies another’s land

· One who kidnap a wife.

Obligation is actually binding when the effect is good, but when the effect is otherwise, then no one can be bound.

Thank you!
