Minds like water seeping from a leaking jug

And those who have no mental vigilance,
Though they may hear the teachings, ponder them or meditate,
With minds like water seeping from a leaking jug,
Their learning will not settle in their memories.

-Sântideva, "Bodhicaryâvatâra"

Sadly, people without any spiritual awareness have no such mental vigilance.

When they hear the teachings, ponder them or meditate, what they hear goes in one ear and out the other!

The best that they can do any student of yoga can do.
