For those who seek to discipline their minds through meditation or other spiritual disciplines, this Buddhist verse will be pause for contemplation:
“Formerly this wandering mind wandered
where it wished, where whim, where pleasure led.
Wisely this day will I restrain it
as trainer with hook an elephant in rut”
From “Treasury Of Wisdom” Dhammapada
It is very true that we must learn to discipline ourselves and our minds before we can proceed very far in our spiritual development. Unfortunately most persons never even realize that this is the point of their presence here.
