Some of my favorites:
A feeling of discouragement when you slip up
is a sure sign that you put your faith in deeds.
Your striving for what is absolutely guaranteed to you
and your laxness in what is required of you
are evidence that your inner eye is dull.
Better to look at the defects hidden within you
than to look for the unseen worlds that are veiled from you.
The Real is not veiled
– it is you that are veiled from seeing Him.
If there was anything veiling Him
what veiled Him would cover Him.
If he was covered,
His existence would be contained.
If something contains something else,
it overpowers it.
But He is the Conqueror, overcoming His slaves.
