There are things known and unknown.
And In Between are the Doors.
Only when you don’t have an answer can you walk through the unknown door.
A closed mind is one that assumes an answer and succeeds only in closing the door to true wisdom. These answers come from the ‘life mind’. The mind that is limited in knowledge.
A clear mind does not find an answer because it understands it only knows a small amount of knowledge and this limited knowledge comes from the conditioned mind.
The clear mind focuses on the question and allows this question to expand until the Universal mind, their Divine delivers the correct answer.
