How do I become more compassionate?
Pained by others' happiness or by their sorrow
One who is pained at seeing others' happiness is a sansari (a worldly person). One who is pained at seeing others' sorrow is a sant. We are pained by a neighbour's happiness and enjoy another's sorrow.
One who feels pain at seeing others' happiness is a worldly person (sansari), and one who feels pain at seeing others' sorrow is a sant. The two are very far apart.
