Judge yourself; if you do that you will not be judged by God, as St. Paul says. But it must be a real sense of your own sinfulness, not an artificial humility.

Often when He comes, He finds the soul occupied. Other guests are there, and He has to turn away. He cannot gain entry, for we love and desire other things; therefore, His gifts, which He is offering to everyone unceasingly, must remain outside.

Give yourself entirely to God, enter and hide in the hidden ground of your soul.

Let God and all his creation teach you what your sins are.
