Moderate effort over a long period of time is important, no matter what you are trying to do. One brings failure on oneself by working extremely hard at the beginning, attempting to do too much,
and then giving it all up after a short time. A constant stream of moderate effort is needed. Similarly, when meditating, you need to be skillful by having frequent, short sessions; it is more
important that the session be of good quality than that it be long.
His Holiness the Dalai Lama
Therefore do not rely on individuals,
But rely upon the Dharma.
Freedom comes from the genuine path that is taught,
Not the one who teaches it.
When the teachings are well presented,
It does not matter what the speaker is like.
Even the bliss-gone buddhas themselves
Appear as butchers and such like to train disciples.
If he contradicts the meaning of the Mahayana and so on,
Then however eloquent a speaker may seem,
He will bring you no benefit,
Like a demon appearing in a buddha’s form.
(Rely on the message of the teacher, not on his personality)
