All God wants of man is a peaceful heart. - Meister Eckhart

There is no better advice on how to find God than to seek him where we left him: do now, when you cannot find God, what you did when last you had him, and then you will find him again.

However a quote very similar to this one can actually be found in his works. In Sermon XXVII (Walshe translation/in Quint Sermon XXXIV) we can read:

Love covers a multitude of sins’ (1 Peter 4:8). For where there is sin, there can be neither complete trust nor love, since love completely covers over sins and knows nothing of them. Not in such a way as if we had not sinned, but rather it wipes them away and drives them out, as if they had never existed.
