Your mind has always been with you, throughout time immemorial. It is not something that can be lost and then found. It is not something one has and then does not have. The mind you have always had is what thinks when you are thinking, and rests without thoughts when you are not thinking. No matter what the mind might be thinking, it is enough simply to relax directly in whatever arises, without trying to alter or adjust anything, and then to sustain that experience without becoming distracted.
