Training of the Mind
As the great ancient Indian Buddhist master Nagarjuna wrote in his Letter to a Friend,
In superior moral discipline, superior wisdom
And superior contemplation, one must constantly train.
More than one hundred and fifty training
Are truly included in these three.
Without the ethical development brought about by training in ethics—“the foundation of all qualities,” according to Nagarjuna—meditation is a spiritual dead end.
As one of the Nyingma masters Mipham Rinpoche explains:
Most settling meditations without analysis
Can produce a mere calm-abiding
But from this meditation certainty will not arise.
If certainty, the one eye of the path of liberation
Is abandoned, the obscurations cannot be dispelled.
