A Vein of Sapphires

I do like ancient Indian poetry, huh? This is by Mahadeviyakka (1130-1180)

A vein of sapphires
hides in the earth
a sweetness in fruit.

And in plain-looking rock
lies a golden ore
and in seeds
the treasure of oil.

Like these,
the Infinite
rests concealed in the heart.

No one can see the ways
of our jasmine-white lord.
