Fear is the memory of PAIIN

Feel PAIIN, think about PAIIN, accept PAIIN, know PAIIN, fear PAIIN.

Even the most ignorant, innocent child will eventually grow up as they learn what true PAIIN is. It affects what they say, what they think… and they become real people.

Love breeds sacrifice... which in turn breeds hatred. Then you can know PAIIN.
