I read horrible news of a desi family in Houston - where parents got killed in Suicide-cum-Homicide and kids are under 'Child Protective Services' (here). Whatever triggered one parent to pull trigger on whole family, reminded me of my Dadi - who use to remind my father during his usual spells of anger.
"Gusse ki aankh nahi hoti"
(Gussa aag ki ruhani shakal hai - jo qaboo main rahe to tuaam ka intazam kerti hai, be-qaboo ho jaaye to ghar jala deti hai - Anger is the spiritual form of Fire. If it remains in line, it creates food, but if gets out of control, it burns the house).
