The first condition is not to have one’s own personal interest as a goal.
The first qualities needed are boldness, courage and perseverance.
And then to be conscious that one knows nothing compared to what one ought to know, that one can do nothing compared to what one ought to do, that one is nothing compared to what one ought to be.
One must have an invariable will to acquire what is lacking in one’s nature, to know what one does not yet know, to be able to do what one is not yet able to do.
One must constantly progress in the light and peace that come from the absence of personal desires.
One could take as a programme:
“Always better. Forward!”
And to have only one goal: to know the Divine in order to be able to manifest Him.
Persevere, and what you cannot do today you will be able to do tomorrow.
