Radiating Kindness

A few lines from the Loving-Kindness chant often replay themselves in my mind. Perhaps you can guess why.

So, with a boundless heart

should one cherish all living beings,

RADIATING kindness over the entire world--

spreading upwards to the skies, 

and downwards to the depths,

outward and unbounded,

freed from hatred and ill-will.

Before they turn on the radiation machine, the radiation technicians leave the room and close the door. Although the radiation is focused on my right breast, bits of radiation are radiating over the entire room, without discrimination.

Can we radiate kindness--without discrimination? Can we radiate kindness, without expecting anything in return?
