हृदय Hrudaya is the emotional heart that empathizes with other conscious beings.
हृदय Hrudaya stems from ह्रद Hrd, the same root as "Heart".
We drop out of analyzing and being judgemental about others and connect in a way that we put ourselves in the other's shoes.
When we see the other person's situation from their perspective we realize that they are just a facet of our own Self.
We take whatever actions are needed, and whatever lesson we can learn, from this perspective shift.
The trick is to do this perspective shift and move on - without getting caught up in stories.
