"At times I achieve according to what I believe.
At times I believe according to what I achieve.
Am I doing the right thing, my Lord?"

"My son, the right thing will be for you
To achieve only what I want you to achieve
And to believe only what I want you to believe.
What I want you to achieve
Is perfect perfection.
What I want you to believe
Is the immortality of your aspiration."
